| 中文摘要 | 实验利用YAG/Nd∶YAG/Cr~(4+)∶YAG键合晶体和光子晶体光栅镜获得高峰值功率和高光束质量的被动调Q径向脉冲激光输出,激光器的输出功率达到435 mW,斜率效率为14.7%。在吸收抽运功率为6.8 W时,输出激光脉冲的峰值功率达到15.7 kW,脉冲能量达到50.1 mJ,脉冲宽度为3.2 ns,重复频率为8.1 kHz,径向偏振纯度为95.8%。实验中的晶体均采用<111>的切割方向,输出径向偏振光束的均匀性得到提高。 |
| 英文摘要 | High peak power radially polarized laser pulse is obtained from a passively Q- switched microchip laser with composite structure of YAG/Nd∶YAG/Cr~(4+)∶YAG crystal and photonic crystal grating mirror as the polarization-selective output coupler. The average output power is 435 mW and a slope efficiency is 15.7%. The laser pulse output has a maximum peak power of 15.7 kW, a minimum pulse duration of 3.2 ns, and repetition rate of 8.1 kHz at absorbed pump power of 6.5 W. The polarization degree of the radially polarized pulse is measured to be as high as 95.8%. All of the crystals in the experiment are <111> cut which is more beneficial for this laser to improve the uniformity of output radially polarized beam. |
