摘要
介绍了自由电子激光光阴极注入器驱动激光器的组成,研究了激光二极管(LD)抽运的连续锁模振荡器的性能,其输出的种子光的平均功率为10.5 W,微脉冲宽度为11.9 ps,时间同步器的时间抖动值为0.56 ps。种子光经脉冲切割与成形,再经三级脉冲激光二极管抽运放大,最后进行四倍频,可以获得波长为266 nm,微脉冲能量为5 μJ的激光脉冲串,脉冲串的宽度为6 μs。
Abstract
The drive laser system of the free electron laser (FEL) radio frequency (RF) photoinjector is introducted. The characteristic of the mode-locked oscillator controlling high current laser diode bar drive is presented in detail. The output power is 10.5 W, the timing jitter of the timing stabilizer is 0.56 ps. 11.9 ps Gaussian pulses of 266 nm wavelength are generated at a repetition rate 54.167 MHz. These “micropulses” are contained within a “macropulse” envelope as long as 6 μs. Micropulse energy of 5 μJ is abtained.
