Abstract

We report the first demonstration of a Raman fiber laser (RFL) emitting in the mid-infrared, above 3 μm. The operation of a single-mode As2S3 chalcogenide glass based RFL at 3.34 μm is demonstrated by using a low-loss Fabry-Pérot cavity formed by a pair of fiber Bragg gratings. A specially designed quasi-cw erbium-doped fluoride fiber laser emitting at 3.005 μm is used to pump the RFL. A laser output peak power of 0.6 W is obtained with a lasing efficiency of 39% with respect to the launched pump power.

摘要

我们首次展示了在中红外区（3μm 以上）发射的拉曼光纤激光器（RFL）。通过使用由一对光纤布拉格光栅形成的低损耗法布里-珀罗腔，演示了基于 As2S3 硫属化物玻璃的单模 RFL 在 3.34μm 处的运行。我们使用专门设计的、在 3.005μm 处发射的准连续掺铒氟化物光纤激光器来泵浦 RFL。在 3.005μm 处发射的准连续掺铒氟化物光纤激光器，获得了 0.6W 的激光输出峰值功率，相对于发射的泵浦功率，激光效率为 39%。
