Narrow-line coherently-combined tapered laser diodes in a Talbot external cavity with a volume Bragg grating

Abstract

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-phase single main lobe mode with a high visibility. We have checked that each emitter is locked to the Bragg wavelength with a 100-pm spectrum linewidth. The experimental results compare well with numerical simulations performed with 2D wide angle finite difference beam propagation method.
