摘　　要：从腔内倍频激光速率方程出发，结合调Q及有效储能时间理论，建立了调Q四能级腔内倍频激光器的数值模型。计算得到了激光峰值功率、脉冲宽度和激光平均功率随脉冲重复频率的变化曲线。经与声光调Q532nm激光器的实测数据比较，模型计算结果与实测数据在1～100kHz的重复频率范围内符合较好。比较结果表明这是一个有效的数值模型。equation, power wit calculated shows tha A numerical model of Q-switched 4-level intracavity frequency doubled laser is proposed based on rate Q-switching and effective energy storage time theory. The calculated peak power, pulse width and average h repetition rate is derived and compared with experimental results of a Q-switched 532 nm laser. The results fit well with the experimental results during the repetition rate range from lkHz to 100kHz which t the numerical model is valid
