  • Laser oscillation amplifier comprising semiconductor laser shaping device
    Publication number: 20230253752
    Abstract: A laser oscillation amplifier includes a seed laser that can produce an input laser beam, a pumping source that can produce a pump light, a semiconductor laser shaping device that can receive the pump light and to produce a shaped pump light, a beam combiner that can combine the shaped pump light and the input laser beam, and a gain fiber coupled with the beam combiner. The gain fiber can absorb the pump light and amplifying the input laser beam to produce an output laser beam.
