ABSTRACT:
It is an object to provide a method of sorting semiconductor lasers, capable of appropriately removing semiconductor lasers which can cause a so-called sudden death in use. After a first current within a range of 50 to 150% the maximum rated current is supplied to the semiconductor lasers for a predetermined period of time, a second current is supplied within a range of 120 to 250% the maximum rated current for a short period of time. Semiconductor lasers which are destroyed or degraded in output characteristics are removed as defective devices.
