| Research Abstract |
In order to establish next generation advanced laser-machining technologies toward low carbon communities, robust, compact and highly stable femtoseocnd high power laser was developed. We have proposed and demonstrated an optical-parametric chirped-pulse amplification scheme in which an even order dispersion of an idler pulse is compensated by passing through an identical positive dispersive material used for temporal stretching a signal pulse. By compressing the idler pulses having a negatively chirp in this manner, high power sub-100 fs pulses were successfully obtained with only a transparent glass block used for the stretcher and compressor.
