展示了具有六个放大器级的高效率、高光束质量二极管泵浦 Nd:YAG 主振荡器功率放大器 (MOPA) 激光器。具有两杆双折射补偿的振荡器被设计为热决定的近半球形谐振器，在108Hz的重复频率下，其脉冲能量为223mJ，光束质量值为M2=1.29。 MOPA系统提供5.1J的脉冲能量，脉冲宽度为230μs，M2因子为3.6，光光效率为38.5%。据我们所知，这是二极管泵浦 Nd:YAG 棒状激光器操作的最高脉冲能量，具有高光束质量和数百微秒的脉冲宽度，重复率超过 100Hz。
A high efficiency, high beam quality diode-pumped Nd:YAG master oscillator power-amplifier (MOPA) laser with six amplifier stages is demonstrated. The oscillator with two-rod birefringence compensation was designed as a thermally determined near hemispherical resonator, which presents a pulse energy of 223mJ with a beam quality value of M2=1.29 at a repetition rate of 108Hz. The MOPA system delivers a pulse energy of 5.1J with a pulse width of 230μs, a M2factor of 3.6 and an optical-to-optical efficiency of 38.5%. To the best of our knowledge, this is the highest pulse energy for a diode-pumped Nd:YAG rod laser operation with a high beam quality and a pulse width of hundreds of microseconds at a repetition rate of over 100Hz.
