Abstract

A high power pico second CO2 laser system is proposed for the generation of high power and high repetition-rated γ-ray beams by Compton scattering. The γ-ray is adopted for the production of positron beams in the Japan Linear Collider (JLC). One hundred independently operated p-sec CO2 laser systems are placed around the Compton interaction point and triggered with the repetition rate of 150 Hz. A reflection mirror system composed of 100 flat mirrors corresponding to each laser unit is placed around the axis of the electron beams. Each p-sec CO2 laser system is composed of a cw-CO2 oscillator, an optical switching section, a pre-amplifier with a regenerative amplifier system and a multiple pass main amplifier.
