Coherent addition of high power laser diode array with a V-shape external Talbot cavity
- Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)
Here, we designed a V-shape external Talbot cavity for a broad-area laser diode array and achieved coherent laser beam addition without using a spatial filter. The V-shape external Talbot cavity provides good mode-discrimination and high-power running capability. Coherent laser beam addition of up to 9-W output power at a narrow spectral linewidth (~0.1 nm) is demonstrated. A multi-lobe far-field profile generated by a low filling-factor phase-locked array is confirmed by our numerical simulation.
