压电陶瓷调制激光回馈外腔的实验和分析OA北大核心CSTPCD
Experiment and analysis of piezoelectric transducer modulated laser feedback external cavity
为了研究微片激光器的光回馈效应的调制方式对激光器光灵敏度的影响,采用不同调制电压、频率驱动压电陶瓷(PZT)来调谐微片激光器外腔的方法,观察光回馈条纹幅值和灵敏度的变化情况,并结合复合腔等效模型进行了数值仿真和分析.结果表明,增大PZT调制频率,使其越靠近激光器的弛豫振荡频率,光放大效果越明显,输出幅值和PZT调制频率具有相同变化趋势;PZT调制频率不变,将140 mA抽运电流调小至出光阈值电流约100 mA,弛豫振荡峰值会逐渐靠近PZT移频调制…查看全部>>
In order to study the influence of the modulation method of the optical feedback effect of the microchip laser on the optical sensitivity of the laser,a method of driving piezoelectric transducer(PZT)with different modulation voltages and frequencies was used to tune the external cavity of the microchip laser,and the changes of the amplitude and sensitivity of the optical feedback fringe were observed.Numerical simulation and analysis based on the composite …查看全部>>
