| 摘 要： | 基于啁啾脉冲放大(CPA)技术和频率变换技术,构建了一个多波长紫外太瓦量级CPA系统.该系统实现了5种频率的精确同步,可同时输出1 Hz,5 Hz和10 Hz的高能量多波段紫外脉冲.时间抖动小于3 ns的时间同步系统和能量不稳定性小于0.5%rms的kHz预放大系统保证了CPA系统输出的能量不稳定性小于2%rms.最后,通过共线相位匹配方案,得到了64 mJ/400 nm,16 mJ/267 nm和5 mJ/205 nm紫外脉冲输出,对应峰值功率达到太瓦量级.

| Abstract: | We set up a multi-wavelength ultraviolet terawatt-order chirped pulse amplification(CPA) system according to the CPA technology and the frequency conversion technology. The system offers 1Hz, 5Hz and 10Hz high energy ultraviolet pulses by precise time synchronization among 5 repeat frequencies. The RMS of output energy fluctuation rate of CPA is less than 2% with using a pre-amplified system of energy fluctuation rate less than 0.3% RMS and a time synchronizer with time jitter less than 3 ns. The multi-wavelength high energy ultraviolet pulses with 64 mJ/400 nm,16 mJ/267 nm and 5 mJ/205 nm are obtained, and their corresponding peak powers reach the terawatt level. |
