Abstract

1. A cooling device for a semiconductor laser fed by an electrical supply source, comprising a refrigerator module which is controlled by a thermal probe, characterized in that said refrigerator module (10, 11) is controlled by a current which is representative only of the electric current passing through the laser (1), said laser thus constituting directly and exclusively said thermal probe for its own cooling control.
