Abstract
A wavelength-stabilized laser configuration has a semiconductor laser and a wavelength regulating device. The regulating device contains an optical isolator, an optical filter, two detectors and a signal processing device. According to the invention, partial beams required for the detectors are coupled out by polarization filters that are contained in the optical isolator and are simultaneously used as beam splitters.
