HIGH OUTPUT CHIRP PULSE AMPLIFIER AND COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a compact and inexpensive high output chirp pulse amplifier from 100 mW to 10 W, and a compressor suitable for the high output chirp pulse amplifier.;SOLUTION: The high output chirp pulse amplifier generating an ultrashort pulse includes a source 10 for generating an elongation pulse, i.e., elongated pulse light, an output amplification stage 20 for amplifying the elongation pulse, and a compressor 40 for receiving the elongation pulse from the output amplification stage 20 and compressing the elongation pulse. The output amplification stage 20 has a double clad fiber and a pump. Preferably, the compressor 40 includes a fiber grid for compressing a laser pulse signal to have a duration less than a threshold of nonlinear effect, and a grating which accepts the pulse signal compressed by the fiber grid so as to compress the pulse signal furthermore. Chirp pulse amplification action of a clad pump fiber ensures high output chirp pulse amplification with a compact and inexpensive amplifier.;COPYRIGHT: (C)2013,JPO&INPIT
