Abstract

A 10 W level 976 nm single-frequency linearly polarized laser source was demonstrated with a two-stage all-fiber amplifier configuration. The continuous-wave output power of 10.1 W was obtained from the second stage amplifier by using a 20/130 μm single-mode, polarization maintaining, 1.5 wt. % ytterbium-doped phosphate double-clad fiber. This all-fiber single-frequency laser source is very promising for watt-level deep ultraviolet laser generation via frequency quadrupling.

摘要

采用两级全光纤放大器结构演示了一个10W级的976nm单频线偏振激光源。通过使用一根20/130μm单模、保偏、1.5wt.%掺镱磷酸盐双包层光纤，在第二级放大器中获得了10.1W的连续波输出功率。这种全光纤单频激光源对于通过四倍频产生瓦级深紫外激光非常有前景。
