Laser module having cooling function, and method of manufacturing the same

摘要

A laser module capable of improving the heat exchange properties between a thermoelectric module and a semiconductor laser than previously possible. The laser module has a thermoelectric module including a plurality of thermoelectric elements and first and second substrates for sandwiching the plurality of thermoelectric elements therebetween, at least the first substrate being made of silicon; and a semiconductor laser formed on the first substrate of the thermoelectric module.
