- 摘要:
- 通过分析准相位匹配光参量振荡器(QPM-OPO)实现参量的过程,分析了基于掺5 mol% MgO:PPLN非线性晶体的准相位匹配光参量振荡器的调谐特性,并在泵浦光一定时给出了相应的调谐曲线.在慢变振幅近似情况下,从耦合波方程出发利用准相位匹配技术的位相匹配关系,推导出掺5 mol% MgO:PPLN非线性晶体光参量振荡系统温度、极化反转畴周期和泵浦光波长匹配带宽的近似解析表达式,并在此基础上给出了相关的理论曲线.
- Abstract:
- By analyzing the character of the process of quasi-phase-matched optical parametric oscillator(QPM-OPO), based on MgO:PPLN discussing the tunability of quasi-phase-matched optical parametric oscillator, and the relative tunable curves are given. Furthermore, the analytical expressions of the temperature, the grating period and the pump wavelength tuning tolerance of 5% MgO-doped Periodically Poled lithium niobate(MgO:PPLN)are deduced based on the general theory of QPM, also the dependence of the theoretical tolerance on the temperature, the grating period and the pump wavelength is given in our work.
