A diode pumped, cw operating, single-mode optical fiber laser emitting at 976 nm

摘要

A single-mode optical fiber laser is made by an optical waveguide segment (2) comprising an inner step-index single-mode waveguide, an outer multi-mode waveguide (11) surrounding the former, and a quartz cladding (12) surrounding said outer waveguide (11). Said inner waveguide (10) is doped with both Nd and Yb and comprises end mirrors (3, 4) adapted for realizing a continuous wave single-mode optical fiber laser device operating in 970-980 nm range. The device is pumped by multi-mode 800 nm GaAlAs laser diode which is coupled at one end of said waveguide segment (2).
