HIGH POWER FIBER CHIRPED PULSE AMPLIFICATION SYSTEM UTILIZING TELECOM-TYPE COMPONENTS

摘要

PROBLEM TO BE SOLVED: To provide a chirped pulse amplifier (CPA) in which the problems and limits of conventional technology are solved.

SOLUTION: The CPA system is equipped with: a mode-locked laser; a polarization holding beam router that is coupled with an output-terminal of the mode-locked laser and that has a first and second output terminals; a polarization holding dispersion compensation fiber that is used for stretching pulse and that is coupled with the first output-terminal of the polarization holding beam router; a first amplifier that is coupled with the polarization holding dispersion compensation fiber; a first pulse selector that is coupled with the first amplifier; a faraday rotator mirror that is coupled with the first pulse selector; and a second amplifier that is coupled with the second output terminal of the polarization holding beam router via a beamsplitter. Input pulse that is inputted into the polarization holding beam router by the mode-locked laser is reflected by the faraday rotator mirror, is returned to the polarization holding beam router, is outputted from the polarization holding beam router and entered into the second amplifier. The first pulse selector is equipped with an integrated modulator with an optical waveguide.
