An efficient and high polarized microchip green laser with dual Nd:YVO4 crystals is reported. The microchip includes a half-monolithic Nd:YVO4-KTP chip and a second Nd:YVO4 crystal. With two 1 W diode lasers pumped, the output power of TEM00 green laser is 430 mW, and the optical-to-optical conversion efficiency is nearly 21.5 %, when the c-axes of second Nd:YVO4 crystal rotated to 90° from the half-monolithic chip, the polarization ratio of output green laser is 130:1. This laser has the advantages of being simple and easily attainable at a low cost, and suitable for batch production. 相似文献

Highly efficient cascaded P-doped Raman fiber laser pumped by Nd:YVO4 solid-state laser 总被引:1,自引:0,他引:1
A highly efficient cascaded P-doped Raman fiber laser (RFL) pumped by a 1064-nm continuous wave (CW) Nd:YVO4 solid-state laser is reported. 1.15-W CW output power at 1484 nm is obtained while the input pump power is 4 W, corresponding to the power conversion efficiency of 28.8%. The threshold pump power for the second-order Stokes radiation is 1.13 W. The slope efficiency is as high as 42.6%. The experimental results are in good agreement with theoretical ones. Furthermore, the power instability of the P-doped RFL at 1484 nm in an hour is observed to be less than 5%. 相似文献

激光二极管端面抽运Nd:YVO4实现1386 nm连续波激光输出 总被引:16,自引:5,他引:11
在Nd:YVO4晶体的4F3/2-4I13/2跃迁带内,除了1342 nm激光辐射之外,其它的跃迁谱线由于小的受激发射截面和强的寄生振荡,很难形成激光振荡.通过调整谐振腔损耗,获得了光纤耦合激光二极管端面抽运1386 nmNd:YVO4激光器激光连续输出.在抽运功率达到4.24 W时,得到了305 mW的1386 nm激光连续输出,最高输出功率下的斜效率为13.9%.实验中还观察到了1342 nm和1386 nm的双波长运转.根据抽运阈值能量和实验数据,计算得到了Nd:YVO4晶体中1386 nm激光辐射处的受激发射截面大约为(3±1)×10-19cm2. 相似文献
