Abstract

PURPOSE:To preferably radiate generated heat at the time of oscillating a laser by forming one or more P-N junctions at a silicon submount interposed between a laser diode and a metallic block stem, thereby interrupting a DC passage unnecessary for the laser oscillation. CONSTITUTION:A laser diode 10 is associated on a silicon submount 20 having good conductivity on a metallic stem 11, is bonded with adhesive of alloy solder having good thermal conductivity, and a laser oscillator is formed. A fine Au wire 15 to the external lead 17 of the stem 11 and a fine Au wire 16 to an external lead 18 insulated and supported to the stem 11 are formed at positive and negative metallic electrodes 6, 7 of the diode 10. A P-N junction 25 by more than one N type layers 23 and P type layers 24 is formed on the mount 20, and when bias is applied to between the leads 17, 18, a DC passage unnecessary for the laser oscillation is interrupted by the P-N junction 25, and the heat generated at the time of laser oscillation is preferably dissipated to alleviate the thermal strain.
