METHOD AND DEVICE FOR OPERATING A LASER LIGHT SOURCE

A method for operating a laser light source including the steps: a) cyclically ascertaining an electrical voltage drop at the laser light source by energizing the laser light source; b) cyclically ascertaining a temperature of the laser light source from the ascertained electrical voltage drop with the aid of a first mathematical connection previously ascertained from the electrical voltage and the temperature of the laser light source; c) ascertaining a current which causes an essentially constant visual output of the laser light source for each ascertained temperature value with the aid of a second mathematical connection from the visual output and the current; and d) energizing the laser light source using this current.
