title: Experimental demonstration of pulse multiplexing and beam combining of four fiber lasers by noncollinear frequency conversion in an LBO crystal.
abstract: In this work, we provide proof-of-concept experimental realization of pulse multiplexing and beam combining of four pulsed Yb-doped fiber lasers by noncollinear frequency up-conversion in an LBO crystal. An overall conversion efficiency of 51% and up to 29 W average power in a combined 532 nm beam were achieved. These results correspond to an improvement by a factor of 2 compared to the average power extracted from a single fiber amplifier.
