Narrow-line coherently combined tapered laser diodes in a Talbot external cavity with a volume Bragg grating
David Paboeuf, Gaelle Lucas-Leclin, Patrick Georges, Nicolas Michel, Michel Krakowski et al.
We present the phase locking of an array of index-guided tapered laser diodes. An external cavity based on the self-imaging Talbot effect has been built. A volume Bragg grating is used as the output coupler to stabilize and narrow the spectrum at 976 nm. A power of 1.7 W is achieved in the in-phas ... [Appl. Phys.
