ABSTRACT:
A frequency conversion diode beam combiner system is provided to multiplex several frequency converted laser beams and therefore keep the beam-quality of a single emitter. This multiplexing is physically impossible with free propagating beams. Both transformations, the frequency conversion and the beam multiplexing, must take place in one step in a single optical component or complex. This also aids the system to be very compact. The frequency conversion diode beam combiner system delivers a single beam which consists of several multiplexed beams from the converted radiation of the diode laser emitters. The high power high beam-quality of this device is not reachable with current diode lasers. A broad range of visible and infra-red wavelengths is possible. The frequency conversion diode beam combiner system can replace high power continuous wave (cw) solid state lasers, because its design is scaleable, small and simple.
