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.
