摘要
在高平均功率激光倍频系统中,非线性倍频晶体吸收剩余能量后温度急剧变化,可能导致相位匹配条件破坏,极大程度地减小倍频转换效率.为了获得高效稳定的倍频输出,研制了一种恒温控制系统,该系统采用新型集成温度传感器AD590探测晶体温度,半导体制冷器调节温度,系统温度精度达0.1℃.
Abstract
In high average power lasers, local heating of frequency doubling crystals induced by the residual absorption at the interacting frequencies leads to the destruction of the perfect phase matching condition, which drastically reduces the conversion efficiencies to the second-harmonic generation. In order to obtain high efficiency SHG output, a temperature control system is developed using a semiconductor cooler to acljust the temperature and a temperature sensor AD590 as the temperature measurement component The temperature accuracy is 0.1 ℃.
