Light-mediated chirped pulse amplifier using idler light while being chirped in the opposite direction

摘要

The light-mediated chirped pulse amplification system according to the present invention, to extend in time by varying the optical path for each frequency laser light, pulse stretcher system giving chirping the method to the preceding short-wavelength (100), the pump pump laser 1 or more to Idemitsu laser light (210, 220), an input (signal light) signals passing through the pulse stretcher system and the pump laser beam, and then amplifies the signal light using the pumping laser beam, the first Light-mediated amplification of the first generating excess light (310), first separates the (signal light and pump light) and non excessive light of the first output light of the light-mediated amplification of the first optical signal separator and 1 (410), the input pump laser light output from the pump laser and other excessive light first separated in the optical signal separation unit of claim 1, using the pump laser beam Light-mediated amplification of the die 2 was amplified surplus light of the first Te, generating the excess light and the second (320), extra light the amplified first output light of the light-mediated amplification of the second and optical signal separator of the second to separate the (excessive light and the second pump light) other than the (420), pulse compression system for compressing in time more extra light first is the amplification ( and characterized in that it comprises, and 600).
