摘要
基于非共线光参量放大,以波长800 nm飞秒激光的倍频光为抽运光,以激光二极管640 nm连续波激光为信号光,产生了与800 nm飞秒激光精确同步的无直流本底的1064 nm脉冲光。实验结果显示该1064 nm的光脉冲在脉冲能量和空间光束质量上均可作为1064 nm波长脉冲放大器的种子光。仅通过一级简单紧凑的非共线参量放大就可实现光周期量级的光参量啁啾脉冲放大系统的抽运激光和种子光的精确同步。
The generation of direct current background-free pulses at 1064 nm that are accurately synchronized with femtosecond pulses at 800 nm is reported by use of a continuous-wave diode laser seeded noncollinear optical parametric amplification pumped by frequency-doubled femtosecond laser at 800 nm. The experimental results show that the laser pulses are quite qualified as the seed pulses of the pulsed laser amplification operating at 1064 nm due to their high pulse energy and spatial beam quality. An accurate all-optical synchronization is realized between pump and signal beams in an optical parametric chirped pulse amplification system just through a single-stage compact noncollinear optical parametric amplifier.
