Abstract
A laser device has a plurality of laser diodes; a plurality of optical elements installed corresponding to the plurality of the laser diodes; a plurality of units formed by fixing the laser diodes and the optical elements per each laser diode and installed corresponding to the plurality of the laser diodes; a converging element that converges laser beams emitted from the plurality of the laser diodes to a fiber; a housing element houses the plurality of the units and the converging element; and a thermal transfer plate performs heat dissipation of the plurality of the units. The heat resistance reducing element having a heat resistance value that is smaller than a predetermined value is installed between the thermal transfer plate and each unit or the processing for reducing the heat resistance is performed.
