| 摘 要： | 为了获得高功率全固态355nm紫外激光器,采用平平腔结构,通过LD双端抽运Nd:YVO4晶体,在声光Q开关调制作用下产生1064nm脉冲基频光,利用两块LBO晶体分别进行腔内倍频、和频产生355nm紫外激光。在LD抽运功率54W、调制频率40kHz的条件下,获得紫外的最高输出功率为6.67W,脉冲宽度为20ns, M2=1.1。结果表明,腔内和频可得到高效率、高光束质量的紫外激光输出。

| Abstract: | In order to get a high power and solid-state UV laser, based on a plane-plane cavity, with laser diode double-end pumping Nd∶YVO4 crystal, fundamental pulse at 1064nm was output under modulation of a acousto-optic Q-switch. Then the laser at 355nm was generated by the second harmonic generation and the third harmonic generation with two LBO crystals. Under the pump power of 54W, 6.67W, average output power at 355nm was obtained at 40kHz with the pulse width of 20ns and M2=1.1. The results show that the design of intra-cavity third harmonic generation lasers can give high conversion efficiency and good beam quality. |
