Abstract

Efficient and compact green-yellow laser output at 543 nm is generated by intracavity frequency doubling of a cw diode-pumped Nd:YVO(4) laser at 1086 nm under the condition of suppressing the higher gain transition near 1064 nm. With 14.5 W of diode pump power and the frequency-doubling crystal LiB(3)O(5), as high as 2.35 W of cw output power at 543 nm is achieved, corresponding to an optical-to-optical conversion efficiency of 15.7%; the output power stability over 5 h is better than 2.56%. To the best of our knowledge, this is the highest watt-level laser at 543 nm generated by intracavity frequency doubling of a diode pumped Nd:YVO(4) laser at 1086 nm.

摘要

高效、紧凑的 543nm 绿光-黄光激光输出是通过在抑制 1064nm 附近的高增益跃迁的条件下，对 1086nm 连续波二极管泵浦 Nd:YVO4 激光腔内进行倍频产生的。在 14.5W 的二极管泵浦功率和 LiB3O5 倍频晶体的作用下，获得了高达 2.35W 的 543nm 连续波输出功率，相应的光-光转换效率为 15.7%；5 小时内的输出功率稳定性优于 2.56%。据我们所知，这是通过腔内倍频 1086nm 二极管泵浦 Nd:YVO4 激光产生的最高瓦级 543nm 激光。
