Driving laser of CW photoinjector

The driving laser is very important in the CW-mode photoinjector. According to the requirement of the CW-mode photoinjector, the output of a CW mode-locked laser can be used as the laser seeds, amplified continuously , and frequency-converted to generate the driving laser. The seeding laser is the diode-pumped self mode-locked laser (GE-100), which can be synchronized to the driving signal through timing stablizer(CLX-100). The repetition rate of laser pulse can be changed from 81.25MHz to 10.16MHz by Pockels’cell, and every laser pulse is cotinuously amplified for 8 times. After forth harmonic, the laser pulse energy can reach 0.3m J at repetition rate of 10.16MHz, and the laser pulse-duration is 5ps.
