Abstract

High-resolution spectroscopy at 125 nm is performed on xenon, using amplified frequency comb pulse trains that are frequency up-converted in a gas cell. It is shown that the phase coherence in the up-conversion process is maintained to better than l/30th of a VUV cycle, thereby demonstrating the potential for sub-MHz accuracy in the vacuum-ultraviolet.

7. Generation of 2 Terawatt Sub-8 fs Laser Pulses using Optical Parametric Chirped Pulse Amplification.

Castleman, A. W., Toennies, J. P., Zinth, W., Yamanouchi, K., Corkum, Paul, Jonas, David M., Miller, R. J. Dwayne., Weiner, Andrew M., Witte, S., Zinkstok, R. Th., Hogervorst, W., and Eikema, K. S. E.

Abstract

We demonstrate the generation of near-Fourier-limited 7.6 fs laser pulses with an intensity of 2 terawatt at 30 Hz repetition rate, using noncollinear optical parametric chirped pulse amplification. A spectrum as wide as 310 nm from a 6.2 fs oscillator laser has been amplified. Compression close to the Fourier-limit of 7.3 fs is achieved with a grating compressor and an LCD phase shaper. Amplified fluorescence is kept below 0.2%, with a pre-pulse contrast of 2×10−8 on picosecond timescales. [ABSTRACT FROM AUTHOR]
