Single-longitudinal-mode Nd-laser with a Bragg-grating Fabry-Perot cavity

• We demonstrate 0.85 W of power in a single longitudinal mode at 1066 nm from a Nd: GdVO4 laser. The laser consists of only two components, the gain medium and a volume Bragg grating in glass, in a simple linear cavity comprising a combination of a Fabry-Perot cavity and a narrowband filter. Thanks to the narrowband Bragg grating, the single longitudinal mode is maintained for a cavity length up to 8 mm, while a continuous tuning of 25 GHz is achieved for a shorter cavity and lower power.
