Abstract
A CAN package light emitting device comprises a semiconductor laserbonded on a sub mountand a CAN packagefor housing the semiconductor laserbonded on the sub mount. The CAN packagecomprises a fixing structurefor fixing the semiconductor laser at a predetermined position, and a capcovering the semiconductor laserfixed to the fixing structure. Vapor pressure of Si organic compound gas in the CAN packageis limited to or below 5.4×10N/mto prevent any deposit as thick as inviting characteristics deterioration from being formed on the light emitting portion of the semiconductor laserwithin the guaranteed time of its proper operation.
