    Passive coherent combining of lasers with phase-contrast filtering for enhanced efficiency

    A new passive technique to phase-lock a laser array is proposed and analyzed. It improves the laser combining efficiency with a large number of emitters. Our architecture combines selective coupling based on a...

    19-cores Yb-fiber laser with mode selection for improved beam brightness

    We propose a new method to control the mode combination at the output of a 19-core fiber laser in order to produce a bright beam with uniform phase. The technique is based on both the selective excitation of t...

    Coherent combining of two Nd:YAG lasers in a Vernier–Michelson-type cavity

    The coherent combining of two Nd:YAG lasers using a Vernier–Michelson-type cavity has been demonstrated. The spectral behaviour and the energetic performance are reported. We firstly show that the combining ef...
