description The present invention relates to a semiconductor laser module and a method for driving the same, wherein an overcurrent limiting means which suppresses the overcurrent to the thermomodule is provided, and it is possible to prevent abnormally high temperature heat being generated from the thermomodule, originating from the overcurrent flow in the heating direction to the thermomodule. Therefore, it is possible to avoid various problems which include thermal breakage of the thermomodule itself, thermal breakage of components such as semiconductor laser elements, etc., thermally connected to the thermomodule, a slip in optical coupling due to a positional deviation of the components originating from high temperature heat, an optical coupling loss, etc. Therefore, the reliability of optical coupling and durability of the semiconductor laser module can be further improved.
