  • Tuneable, adjustment-stable semiconductor laser light source and a method for the optically stable, largely continuous tuning of semiconductor lasers
    Patent number: 6785305
    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.

  • Tunable alignment-stable laser light source having a spectrally filtered exit
    Patent number: 6038239
    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.
