Optimization of diode-pumped doubly QML laser with neodymium-doped vanadate crystals at 1.34 μm

We present a theoretical model for a diode-pumped, 1.34 μm V³⁺:YAG laser that is equipped with an acoustic-optic modulator. The model includes the loss introduced by the acoustic-optic modulator combined with the physical properties of the laser resonator, the neodymium-doped vanadate crystals and the output coupler. The parameters are adjusted within a reasonable range to optimize the pulse output characteristics. A typical Q-switched and mode-locked Nd:Lu_0.15Y_0.85VO₄ laser at 1.34 μm with acoustic-optic modulator and V³⁺:YAG is set up, and the experimental output characteristics are consistent with the theoretical simulation results.
