设计了一种用于替代现有商业化1053nm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3160nm中红外激光脉冲,然后利用三倍频(THG)方式,实现高信噪比1053nm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。
A scheme was designed to replace the existing commercial 1053nm femtosecond mode-locked laser oscillator. The scheme achieves energy amplification and wavelength conversion by optical parametric chirped pulse amplification (OPCPA) to generate a 3160nm mid-infrared laser pulse as a fundamental frequency light and then uses a triple frequency (THG) mode to achieve a high signal-to-noise 1053nm pulse output . The application of this scheme is expected to enhance the front-end signal-to-noise ratio of the pico-watt laser device, thereby improving the output signal-to-noise ratio of the whole device.
