  • High power multi-frequency laser
    Patent number: 7020168
    Abstract: A high power multi-frequency laser includes a laser cavity defined by reflective elements, a frequency routing device in the cavity comprising a plurality of frequency selective pathways, a first set of optical amplifiers optically coupled to a first end of the frequency routing device, and a second set of optical amplifiers optically coupling a second end of the frequency routing device and a first one of the reflective elements. The high power multi-frequency laser further includes a power combiner. The power combiner is optically coupled to the first set of optical amplifiers and a second one of the reflective elements and combines the outputs of the first set of optical amplifiers such that a common output for the multi-frequency laser is provided. The common output of the present invention provides a single output from the multi-frequency laser having a high output coupling efficiency.
