摘要
研究了控制单纵模Nd:YVO_4微片激光器光谱稳定的方法,实现了在不同LD泵浦电流条件下单纵模Nd:YVO_4微片激光器的波长稳定输出。首先,分析了泵浦电流、温控温度与晶体温度、输出激光波长的关系,发现在不同泵浦电流条件下,适当调节温控温度控制Nd:YVO_4微片晶体的温度变化,能够实现激光光谱的稳定控制。最后,通过实验验证了该方法的有效性,并获得激光输出功率随泵浦电流变化的非线性关系。
The spectral stability of the single longitudinal mode Nd：YVO4 microchip laser was experimentally investigated.. The stable spectrum of the single mode Nd：YVO4 microchip laser under different pump current conditions was achieved. Firstly, the relation of the LD pump current and the temperature controller to the crystal temperature and the output laser wavelength is analyzed. It is found that the laser spectrum stability control will be achieved when the temperature change ofNd：YVO4 microcry^tal controlled by the temperature controller is adjusted rationally under different pump current conditions. Finally, the effectiveness of the method is verified by the experimental results, and the nonlinear relationship between the laser output power and the LD pump current is obtained.
