摘要
研究了外腔钨酸铅(PbWO4)拉曼激光器的输出特性,介绍了由1064nm纳秒脉冲激发的PbWO4固态拉曼放大器。实验所用的抽运源是电光调Q的Nd…YAG纳秒激光器。对于外腔PbWO4拉曼激光器,当入射抽运脉冲能量为40mJ时,实验测得一阶斯托克斯脉冲的最大转换效率为13%,当入射抽运脉冲能量为48mJ时,实验得到包括一阶斯托克斯脉冲在内的总散射光的转换效率为34%,获得的二阶斯托克斯脉冲的转换效率为23%。PbWO4拉曼放大器是对外腔PbWO4拉曼激光器产生的一阶斯托克斯脉冲进行放大,实验获得的放大后一阶斯托克斯脉冲的最大输出能量为11mJ,放大倍数为3.3。
The output properties of an extracavity PbWO4 Raman laser are investigated. A PbWO4 solid Raman amplifier is also presented. The extracavity PbWO4 Raman laser and PbWO4 solid Raman amplifier are both pumped by an electro-optically Q-switched Nd： YAG laser. For the extra cavity PbWO4 Raman laser, with incident pulse energy of 40 mJ, the obtained maximum conversion efficiency of the first Stokes is 13 %. When the pump energy is 48 mJ, the obtained maximum pulse energy and conversion efficiency of the second Stokes are 11 mJ and 23%, and the conversion efficiency of the full scattering laser is 34 %. For the PbW04 solid Raman amplifier, the maximum output energy of the amplifying first Stokes pulse and the amplification factor are 11 mJ and 3.3.
