Abstract

Based on the rate equation of four-level system and numerical simulation, the phase-matching characteristic of laser-diode-pumped Nd:GdVO₄/KBe₂BO₃F₂(KBBF) solid-state laser has been studied. The influences of pumping and oscillating spot size to output power and laser threshold with different gain medium are studied. Compared to CsLiB₆O₁₀ (CLBO) and β-BaB₂O₄ (BBO), the phase-matching characteristics of the nonlinear optical crystal KBBF are carried out through numerical simulation. For type I and type II phase-matching condition, KBBF which is more easy to realize ultraviolet laser output has shorter transmission bandwidth and broader tunable phase-matching angle than CLBO and BBO. It is useful to optimize and select the parameters of such systems.
