Abstract
A laser unit containing a laser package, in which a laser element has been hermetically sealed, is connected with a converging optical system unit containing a converging optical system. The laser unit is provided with a laser package holder, which comprises a holder main body for supporting the laser package and a connecting member. The converging optical system unit is provided with a converging optical system holder, which comprises a holder main body for supporting the converging optical system and a connecting member having been welded to the connecting member of the laser package holder. A thermal conductivity of the holder main body of the laser package holder is set to be larger than the thermal conductivities of the connecting member of the laser package holder and the connecting member of the converging optical system holder.
