ABSTRACT:
A CAN package light emitting device comprises a semiconductor laser1bonded on a sub mount6and a CAN package2for housing the semiconductor laser1bonded on the sub mount6. The CAN package2comprises a fixing structure3for fixing the semiconductor laser at a predetermined position, and a cap4covering the semiconductor laser1fixed to the fixing structure3. Vapor pressure of Si organic compound gas in the CAN package2is limited to or below 5.4×102N/m2to prevent any deposit as thick as inviting characteristics deterioration from being formed on the light emitting portion of the semiconductor laser1within the guaranteed time of its proper operation.
