Description
Eotron has developed a method of coherently beam combining using a circular diffraction grating to improve a beam quality and efficiency of semiconductor lasers. Instead of using a linear grating to combine multiple diode emitters in spectral beam combining (SBC) technique, we have developed to use a circular grating to combine in 2D diode emitters to produce coherent beam combining along with a passive optical component in an external cavity design. Such a novel design of beam combining technique produces a better beam quality and higher efficiency in a compact form-factor to meet military and commercial applications. A high-power direct diode laser built by this technique will improve on the cost structure of direct diode laser and better beam quality for next generation of laser system design.
