实验研究了Nd：YVO₄/Nd：GdVO₄双波长激光器在不同抽运功率条件下，通过调节热沉温度达到功率均衡时的输出特性.实验结果表明：对于Nd：YVO₄/Nd：GdVO₄双波长激光器，当提高抽运功率，需要重新降低热沉温度达到功率均衡输出，降温幅度与抽运功率增加之比为11.23℃/W.与此同时，随着抽运功率和热沉温度的变化，双波长激光器的中心波长会出现小幅度的漂移，左峰波长随抽运功率增加的蓝移速率为0.056 nm/W，右峰波长随抽运功率增加的蓝移速率为0.054 nm/W.实验还发现功率均衡条件下激光器的输出总功率随抽运功率的增加而增加，拟合斜效率为8.7%，当抽运功率为5.58 W时，输出最大总功率达到115.7 mW.

The output characteristics of the power-balanced Nd:YVO₄/Nd:GdVO₄ Dual-Wavelength Laser (DWL) under different pumping conditions is investigated experimentally. The experimental results show for power-balanced Nd:YVO₄/Nd:GdVO₄ DWL, the heat sink temperature needs reduce when the pumping power increases, and the ratio of temperature decreasing versus pumping power increasing is 11.23 ℃/W. With the change of pumping power and heat sink temperature, the DWL wavelengths shift slightly. When the pumping power increases, the DWL left wavelength blue-shifting rate is 0.056 nm/W, and the right wavelength one is 0.054 nm/W. The result also found that the output power of the power-balanced DWL increases with the pumping power increasing. The fitted slope efficiency is 8.7%. When the pumping power is 5.58 W, the maximum output power reaches 115.7 mW.
