摘要
设计了一种用于替代现有商业化1053 nm飞秒锁模激光振荡器的方案。该方案通过光参量啁啾脉冲放大技术(OPCPA)实现能量放大和波长变换，产生作为基频光的3160 nm中红外激光脉冲，然后利用三倍频(THG)方式，实现高信噪比1053 nm脉冲输出。该方案的应用有望提升拍瓦激光装置的前端信噪比，进而改善整个装置的输出信噪比。
Abstract
A novel device is designed to replace the commercial 1053 nm femtosecond mode-locked laser oscillator. In this device, optical parametric chirped pulse amplification (OPCPA) is applied to realize energy amplification and wavelength conversion, and 3160 nm mid-infrared laser pulse is produced as the fundamental wave. Then a high signal to noise ratio (SNR) 1053 nm output pulse is got by the third harmonic generation (THG) process. The application of this device is expected to enhance the SNR of petawatt front-end and improve the SNR of the whole petawatt system at the same time.
