Compressor and high-power chirped pulse amplification system

摘要

PROBLEM TO BE SOLVED: To provide a small-sized high output chirp pulse amplifier device of 100mW-10W and a compressor suitable for the same device. ;SOLUTION: This device is provided with a generation source 10 generating an expansion pulse being expanded pulse light, an output amplifier stage 20 amplifying the expansion pulse and the compressor 40 receiving the expansion pulse from the output amplifier stage 20 and compressing it, and the output amplifier stage 20 is provided with a double clad fiber and a pump, and the device is the high output chirp pulse amplifier device generating a super short pulse. The compressor 40 is preferred to be provided with a fiber grating compressing a laser pulse signal to a duration time of a threshold value or below of a non-linear effect and a diffraction grating receiving the pulse signal compressed by the fiber grating for further compressing the pulse signal. By a chirp pulse amplifier action of a clad pump fiber, chirp pulse amplification of a high output though it is miniaturized and inexpensive is made possible.;COPYRIGHT: (C)1997,JPO
