Abstract

A semiconductor light source (1), whose wavelength and preferably also its output power are stabilised in a highly precise manner in that the laser current (Io) or a portion of the laser beam is modulated, is advanced through a wave selection filter (13) and, after detection, a control signal is provided to the semiconductor via a phase-sensitive amplifier (16) and a comparator (19). Wavelength stabilisation to 10<-9> and output power regulation to better than 10<-3> can be attained,
