摘　　要：利用四块Nd…YVO_4晶体,采用主振荡功率放大结构对全固态连续单频1064nm激光种子源进行四级放大,实现了实验级别的百瓦级连续单频1064nm激光源输出。注入抽运功率为220.00 W时,放大级最大输出功率为103.80W,总的光光转化效率为33.2%。激光放大器的输出功率为97.73W时,激光放大器的长期功率稳定性在5小时内优于±0.53%,光束质量因子M^2<1.38,强度噪声在4.3 MHz处达到了量子噪声极限。By utilizing the master oscillator power amplifier configuration which includes a continuous-wave single- frequency 1064 nm seed laser and four-stage Nd： YVO4 amplifier, a continuous-wave single-frequency 1064 nm laser is realized experiment ally. When the pump power is 220.00 W, the highest output power reaches 103.80 W and the total optical-optical efficiency of the amplified laser is 33.2%. When the output power of the amplified laser is 97.73 W, the long-term power stability within five hours is better than ±0.53% and the beam quality factor Mz is less than 1.38. The intensity noise reaches the quantum noise limit of 4.3 MHz.
