“…The idea of inserting a wavelength-dependent loss in a regenerative amplifier to compensate for gain narrowing was proposed and demonstrated by Barty et al more than 10 years ago [46]. Since then, there have been many attempts to control the amplified spectrum in a CPA laser system [46][47][48][49][50].…”

We have developed a laser system generating high peak-power ultrashort pulses based on the chirped pulse amplification of a Ti:sapphire laser. The pulse duration of the laser is reduced to 12 fs, owing to the successful compensation of gain narrowing during amplification with novel optics. The pulse energy and the repetition rate are 40 mJ and 100 Hz, respectively, as a consequence of sufficient energy extraction from a laser medium in the final stage of a multipass amplifier chain, which is designed to balance focusing with a thermal lens against defocusing with convex mirrors without cryogenic cooling for Ti:sapphire crystals. The laser pulses delivered from this laser system are suitable for generating an intense attosecond pulse train in a vacuum ultraviolet or extreme ultraviolet region.

“…8 Researchers have employed various schemes incorporating prisms, complex stretcher -compressor designs, and ultrahigh-precision optics to compensate for up to the fourth-order phase in a Taylor expansion. 2,9,10,11 However, very complex phase aberrations can arise from the use of chirped mirrors 12 and intracavity etalons 13 in an amplifier system; to date, these aberrations have been impossible to compensate for completely. Recently, pulse shapers with liquid crystals 14 have been used to adaptively correct 15 for amplifier-induced spectral phase distortions.…”

Adaptive pulse compression for transform-limited 15-fs high-energy pulse generation

We demonstrate the use of a deformable-mirror pulse shaper, combined with an evolutionary optimization algorithm, to correct high-order residual phase aberrations in a 1-mJ, 1-kHz, 15-fs laser amplif ier. Frequencyresolved optical gating measurements reveal that the output pulse duration of 15.2 fs is within our measurement error of the theoretical transform limit. This technique signif icantly reduces the pulse duration and the temporal prepulse energy of the pulse while increasing the peak intensity by 26%. It is demonstrated, for what is believed to be the f irst time, that the problem of pedestals in laser amplif iers can be addressed by spectral-domain correction.  2000 Optical Society of America OCIS codes: 140.7090, 140.3590, 320.5540, 320.5520.The past five years have seen considerable improvements in the capabilities of high-power ultrafast lasers. Ti : sapphire-based oscillator-amplifier systems can generate peak powers of ϳ100 TW at 10 Hz, or 0.3-1 TW at kilohertz repetition rates.
