Abstract: The preferably highly antireflection coated facet of a laser chip is imaged by an optical system onto a reflector, as a result of which the adjustment tolerance is substantially increased by the cat's eye effect and, since the optical system is provided with a high longitudinal chromatic aberration, the wavelength can be tuned by shifting given parts of the total system relative to other parts of the total system. In this way a tunable semiconductor laser light source which is free from mode jumps and has at most two adjustable degrees of freedom can be produced.

Abstract: The invention relates to a laser light source having a broadband-amplifying and narrowband-tunable active medium, which involves an uncomplicated arrangement and is remarkable for the specific suppression of the broadband spontaneous emission and the side modes as well as for its optical stability. It included a laser medium itself, a preferably diffraction-limited optical system, an angular- or linear-dispersing element, and a reflector, the preferably plane reflector being arranged so as to form a retroreflector according to the cat's eye principle together with the imaging system, the reflector in addition being designed so as to be partially transmitting, and at the same time, a preferably non-reflecting space filter also being situated at least approximately in the plane of the reflector, so that only spectrally filtered radiation may pass the space filter, so that only the latter reaches the reflector, and there, separation of back-coupled and decoupled, usable radiation being effected at one single surface.
