  • Mid-infrared laser system, mid-infrared optical amplifier, and method of operating a mid-infrared laser system
    Patent number: 10084287
    Abstract: The mid-infrared laser system has an amplifier including at least one pump laser adapted to generate a pump laser beam and a length of fiber made of a low phonon energy glass and having at least one laser-active doped region between a first end and a second end, and a seed laser to generate a seed laser beam having a seed optical spectrum in the mid-infrared. The seed laser beam is launched into the first end to generate a mid-infrared laser beam outputted from the second end via stimulated emission upon pumping of the at least one laser-active doped region with the pump laser beam. When the power of the pump laser exceeds a spectrum modification threshold, the mid-infrared laser beam has an output optical spectrum being broadened relative to the seed optical spectrum.
