Optics Express, 19(23), 23315-23326.More infoPMID: 22109209;Abstract: Previous work has shown that use of a passive enhancement cavity designed for ultrashort pulses can enable the up-conversion of the fs frequency comb into the extreme ultraviolet (XUV) spectral region utilizing the highly nonlinear process of high harmonic generation. This promising approach for an efficient source of highly coherent light in this difficult to reach spectral region promises to be a unique tool for precision spectroscopy and temporally resolved measurements. Yet to date, this approach has not been extensively utilized due in part to the low powers so far achieved and in part due to the challenges in directly probing electronic transitions with the frequency comb itself. We report on a dramatically improved XUV frequency comb producing record power levels to date in the 50-150nm spectral region based on intracavity high harmonic generation. We measure up to 77 μW at the 11th harmonic of the fundamental (72nm) with μW levels down to the 15th harmonic (53nm). Phase-matching and related design considerations unique to intracavity high harmonic generation are discussed, guided by numerical simulations which provide insight into the role played by intracavity ionization dynamics. We further propose and analyze dual-comb spectroscopy in the XUV and show that the power levels reported here permit this approach for the first time. Dual-comb spectroscopy in this physically rich spectral region promises to enable the study of a significantly broader range of atomic and molecular spectra with unprecedented precision and accuracy. © 2011 Optical Society of America.

Springer Series in Optical Sciences, 132, 59-64.More infoAbstract: High-harmonic generation (HHG) [1],[2] provides a coherent source of vacuum ultraviolet (VUV) to soft X-ray radiation in a relatively compact system. Since its first observations [3],[4], HHG has relied on high-energy, low repetition rate laser systems to provide the peak intensities needed for ionization of the gas target. The small conversion efficiency of the process, combined with the low repetition rate of amplified laser systems, results in low average powers in the VUV generation. Experiments trying to utilize these sources therefore often suffer from poor signal-to-noise levels, resulting in long data-acquisition times. Furthermore, the use of these sources as precision spectroscopic tools remains limited in comparison with sources in the visible. Ramsey-type spectroscopy has been utilized to improve spectral resolution in the VUV [5],[6] but remains orders of magnitude away from the precision measurement capability available with fs laser based frequency combs in the optical and IR [7],[8]. This is due to the fact that the original frequency comb structure of the laser is lost in the HHG process from the reduction of the pulse train repetition rate required to actively amplify single pulses to the needed energies/intensities. © 2007 Springer-Verlag New York.

Science, 311(5767), 1595-1599.More infoPMID: 16543457;Abstract: We demonstrate highly efficient cavity ringdown spectroscopy in which a broad-bandwidth optical frequency comb is coherently coupled to a high-finesse optical cavity that acts as the sample chamber. 125,000 optical comb components, each coupled into a specific longitudinal cavity mode, undergo ringdown decays when the cavity input is shut off. Sensitive intracavity absorption information is simultaneously available across 100 nanometers in the visible and near-infrared spectral regions. Real-time, quantitative measurements were made of the trace presence, the transition strengths and linewidths, and the population redistributions due to collisions and the temperature changes for molecules such as C2H2, O2, H2O, and NH3.

With servo control from the EOM (bandwidth ∼230 kHz) and a slower speed intracavity piezoelectric transducer (resonance at ∼20 kHz), we demonstrate stabilization of the repetition frequency with an in-loop rms timing jitter of 10 fs, integrated over a bandwidth from 1 Hz to 100 kHz.

Physical Review Letters, 94(19).More infoAbstract: We demonstrate the generation of phase-coherent frequency combs in the vacuum utraviolet spectral region. The output from a mode-locked laser is stabilized to a femtosecond enhancement cavity with a gas jet at the intracavity focus. The resulting high-peak power of the intracavity pulse enables efficient high-harmonic generation by utilizing the full repetition rate of the laser. Optical-heterodyne-based measurements reveal that the coherent frequency comb structure of the original laser is fully preserved in the high-harmonic generation process. These results open the door for precision frequency metrology at extreme ultraviolet wavelengths and permit the efficient generation of phase-coherent high-order harmonics using only a standard laser oscillator without active amplification of single pulses. © 2005 The American Physical Society.

We find that for χ(3) nonlinearities, when a train of femtosecond pulses are maximally coupled into a cavity by active stabilization of its frequency comb to the corresponding linear resonances of a cavity, enhancement ceases when the peak nonlinear phase shift is sufficient to shift the cavity resonance frequencies by more than a cavity linewidth. In addition, we study and account for the complex spectral dynamics that result from chirping the input pulse and show excellent qualitative agreement with experimental results. © 2005 Optical Society of America.

Optics Express, 13(3), 882-888.More infoPMID: 19494950;Abstract: We precisely determine the dispersion of an optical cavity over a large spectral bandwidth using a broadband optical comb generated by a femtosecond laser. This approach permits the effective characterization of the next generation of mirrors that will offer high reflectivity, minimal absorption/scattering loss, and well-defined dispersion characteristics. Such mirrors are essential for constructing passive, high-finesse cavities capable of storing and enhancing ultrashort pulses and for exploring novel intracavity-based experiments in atomic and molecular spectroscopy and extreme nonlinear optics. We characterize both zero and negative group-delay-dispersion mirrors and compare their performance against the targeted coating design. The high sensitivity of this approach is demonstrated with a precise determination of the group-delay dispersion of air inside a 40-cm long optical cavity, demonstrating an accuracy better than 1 fs2. © 2005 Optical Society of America.

Journal of Modern Optics, 49(14-15), 2517-2533.More infoAbstract: Our ultimate objective is to design a combined frequency standard for optical as well as radio frequencies. A mode-locked laser provides frequency components that can be used as a ruler to measure any unknown optical source through direct beating. The frequency spacing of a pair of teeth of this comb is in itself a radio frequency reference. Fast control and correction for both the average frequency and the repetition rate of a mode-locked Ti:sapphire laser are achieved by locking the laser to a reference cavity of ultra-low expansion quartz with equal mode spacing. We measure an optical frequency with a mean square deviation of 700 Hz, instability limited by the radio-frequency sources used to count the repetition rate. As a reference standard to achieve absolute accuracy, we use the Λ transition 5S1/2(F = 1) → 5D5/2(F = 3) → 5S1/2(F = 2) of rubidium. The theory for this coherent interaction shows that, with one mode resonant with the two-photon 5S1/2(F = 1) → 5D5/2(F = 3) transition, the fluorescence goes through a resonance for a change in repetition rate of less than 10kHz. These results suggest that, by locking to the peak of that resonant feature, optical stability and absolute accuracy better than 1 kHz can easily be achieved.

An optical Cavity can be used for coherent delay and constructive interference of sequential pulses until a cavity dump is enabled to switch out the amplified pulse. This approach will lead to an effective amplification process through decimation of the original pulse rate while the overall coherence from the oscillator is preserved.

This paper presents one of the systems based on an optical transition of iodine molecules, providing an rf clock signal with a frequency stability comparable to that of an optical standard, and that is superior to almost all conventional rf sources.

Blue radiation emanating from the crystal was identified as surface second harmonic and sum frequency generation. The latter appearing only in condition of bidirectionality, provides a convenient means to verify that pulses are indeed crossing in the nonlinear crystal.

The sensitivity of the ring laser as a probe for non-reciprocal effects results from the fact that the difference between cavity perimeters in either direction is being probed. The beat note between the two pulse trains provides the error signal needed for stabilization. In the stabilized laser, any change in rotation of the laser support appears as an error signal in the feedback.

Conference on Lasers and Electro-Optics Europe - Technical Digest, 434-.More infoAbstract: Bias-free bidirectional operation of a Ti:sapphire laser has been obtained through the use of a ZnS crystal as Kerr-lensing element. Two types of cavity configuration have been investigated. The Ti:sapphire crystal is located symmetrically with respect to the cavity waist. A ZnS crystal is located close to an auxiliary waist in the cavity. The circulating phase has been found to be naturally symmetric for both directions. However, there is a lock-in effect associated with the scattering of each pulse into each other at their meeting point in the ZnS crystal. This lock-in can be eliminated by either motional dithering or electro-optic dithering.
