Abstract: The invention relates to wavelength stabilization and wavelength multiplexing of multiple high-power multi-mode semiconductor lasers. The lasers are wavelength-stabilized in free space using multi-peak output reflectors to wavelength-lock their output at different reflection wavelength in dependence on operating conditions, to reduce output reflectivity required for locking and increase output power. Selecting output reflectors having different non-overlapping sets of reflectivity peaks for different lasers or groups of lasers enables combining their output by wavelength multiplexing.

Abstract: A laser diode assembly is disclosed, in which a transmissive reflector is used to redirect the laser beam upwards or to turn or rotate the laser beam. The reflector has at least one Brewster transmissive surface and at least one total internal reflection surface. Several total internal reflection surfaces rotated with respect to one another may be used in a single reflector to redirect and rotate the laser diode beam.

Abstract: The use of one or more angled or curved and diverging light pipes or reflectors placed in a light source's, e.g. diode's, emission path at appropriate distances, angles and divergence, such that a diode's emission spot size is modified and or redirected from the diode's natural emission path to alternative planes at angle to the diode's natural emission path so that a diode emission safe spot size can be achieved on any plane at angle to the original diode natural emission path at minimum distances from the diode's point of emission.
