【Abstract】 A piece of cylindrical microlens is used to collimate the output radiation of a laser diode bar in the fast axis direction. The emissions of the laser diode bar are coupled into multimode fiber array. The output power of laser diode module is up to 60 W. The coupling efficiency is more than 80 %. The numerical aperture of the fiber is 0.11.更多还原
