Abstract : The patent describes a laser system that provides simultaneous operation of any two laser transitions occuring in an infrared laser. A chemical active element is in combination with a germanium flat that polarizes and spatially separates the two laser beams such that their polarizations are perpendicular to each other and directs the laser beams to separate gratings. Each grating is rotated to select and reflect a laser beam of a particular wavelength back through the system so that two particular beams are directed from the output.
