Compensation of higher order dispersion on idler pulse compression scheme, 1; Phase measurement of interacting pulses on OPA

Akahane, Yutaka; Tomita, Hitoshi*; Ogawa, Kanade; Nishioka, Hajime*; Yamakawa, Koichi

no journal, , 

Spectral phases of interacting (signal, idler, pump) pulses on optical-parametric amplification process were measured, aimed for compensating higher order dispersion on compressed idler pulses by phase modulation on pump pulses in optical-parametric chirped-pulse amplification. An wide-time-range spectral-shearing interferometry developed very recently was applied to these phase measurement, which is capable for measuring picosecond chirped pulses unsuitable for SPIDER phase measurement formerly. In the measurement, some variations of spectral dispersions on idler pulses caused by phase modulation on pump pulses were observed, which enables us to control spectral dispersions of idler pulse by manipulating spectral phases of pump pulses.

Development of robust intense femtosecond laser with positive dispersive media for both pulse stretcher and compressor

Akahane, Yutaka; Ogawa, Kanade; Tomita, Hitoshi*; Nishioka, Hajime*; Yamakawa, Koichi

no journal, , 

We have proposed and demonstrated a novel chirped-pulse amplification (CPA) scheme which idler pulses in optical-parametric chirped-pulse amplification have been compressed with an identical positive dispersive media as signal pulse stretcher. With this idler compression scheme simple, robust and efficient CPA laser can be realized for industrial applications. In the demonstration experiment, sub-100 fs compressed idler pulses successfully obtained.
