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 stabilizer(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 continuously amplified for 8 times. After forth harmonic, the laser pulse energy can reach 0.3 μJ at repetition rate of 10.16MHz, and the laser pulse duration is 5ps.
