Laser Design and Applications

Laser electron Compton scattering monochromatic tunable X-ray source using X-band (11.424 GHz) electron linear accelerator and Q-switch Nd:YAG laser is under construction at Nuclear Professional School, the University of Tokyo. To enhance the X-ray intensity, we installed a laser circulation system. Now, we are performing the circulation experiment by using a high power laser (1.4 J, 532 nm). We confirmed the laser pulse circulated in the optical circuit more than 15 times and the laser intensity is enhanced about 3.5 times.
