Diode-pumped All-solid-state Red Laser of Nd:YVO4/PPLT
摘要
报告了使用周期极化的钽酸锂超晶格(PPLT)对二极管抽运Nd:YVO4 1342 nm谱线进行腔外直接单通倍 频获得有效671 nm红光输出的研究结果。实验所用样品长为20 mm,周期为14.77 μm。获得的最髙红光输出平 均功率为840 mW,此时808 nm抽运光的功率为12.3 W,总的光-光转换效率达到6.8%。在1342 nm的基波光功 率为647 mW时, 得到从1342 nm到671 nm的转换效率为63%。另外,在连续波模式下测得样品的有效非线性系 数为 3.8 pm/V。
Abstract
Ail efficient red light generation in a periodically poled LiTaQ (PPLT) by extracavity single-pass frequency doubling of a diode-pumped Nd:YVO4 laser at 1342 nm is reported. The sample used in the experiment is 20 mm in length and 14. 77 μm in period. The maximum output power of the 671 nm red laser is 840 mW, when the pump power of 808 nm is 12.3 W. The overall optical-to-optical efficiency is 6.8%. An internal conversion efficiency of 63% is obtained when fundamental power of 1342 nm is 647 mW. The measured effective nonlinear coefficient under the CW mode of the sample is ~4.6 pm/V.
