Abstract—A new three-matrix mixed vanadate crystal Nd:Lu_0.33Y_0.36Gd_0.3VO₄ (Nd:LuYGdVO₄) crystal was
grown by the Czochralski method. Room temperature absorption and fluorescence spectra of the
Nd:LuYGdVO₄ crystals were measured and the spectroscopic parameters were calculated by the Judd–Ofelt
theory. The intensity parameters of the Nd:LuYGdVO₄ crystal were ₂ = 9.736 10^–20 cm², ₄ = 4.179
10^@@20 cm², ₆ = 8.020 10^–20 cm² and the stimulate emission cross section was 5.3 10^–19 cm². Diode-
pumped actively Q-switched and passively Q-switched Nd:LuYGdVO₄ and Nd:Lu_0.14Y_0.86VO₄ lasers at 1.06
m were demonstrated. The results indicate that, for both actively and passively Q-switched lasers, the
Nd:LuYGdVO₄ lasers can generate shorter pulse width with higher peak power than the Nd:Lu_0.14Y_0.86VO₄
lasers at the same cavity conditions.
