双频微片激光器的功率均衡机制实验研究

为了研究双频Nd∶YVO4微片激光器的功率均衡机制, 利用实验研究分析了微片激光器的抽运电流、工作温度和谐振波长等参量之间关系。不断增大双频激光器抽运电流, 通过降低晶体温度不断重新实现双频激光功率的均衡, 最终获得了不同抽运电流下的双频激光器的功率均衡温度, 以及双频功率积与抽运电流的关系数据。结果表明, 双频激光信号功率均衡温度与抽运电流呈分段负相关, 双频功率积与抽运电流呈正相关。此结果说明通过改变抽运电流和温控温度可以实现功率可调的功率均衡的双频激光信号输出。

Abstract

In order to investigate output power balance mechanism of Nd∶YVO4 microchip dual-frequency lasers (DFL), the relationships among pump current, operating temperature and dual-mode wavelengths of microchip lasers were analyzed by means of experiments. With the increase of pump current of DFL, the balance of DFL power was re-achieved by lowering the temperature of laser crystal. Finally, the power-balanced temperature of DFL with different pump currents and the relationship between dual-frequency power product and pump current of DFL were obtained. The result shows that, the power-balanced temperature of DFL signal is negatively correlated with pump current sectionally, and dual frequency power product is positively correlated with pump current. It indicated that, power-balanced power-adjustable dual-frequency laser signal output can be achieved by changing pump current and controlling temperature.
