  • High power long wavelength pulsed IR laser system with highly variable pulse width and repetition rate
    Patent number: 11482834
    Abstract: A laser system produces pulses having wavelengths between 2000 nm and 2100 nm, peak output powers greater than 1 kW, average powers greater than 10 W, pulse widths variable from 0.5 to 10 nsec, pulse repetition frequencies variable from 0.1 to over 2 MHz, and a pulse extinction of at least 60 dB. Pulses from a diode laser having a wavelength between 1000 nm and 1100 nm are amplified by at least one fiberoptic amplifier and applied as the pump input to an Optical Parametric Amplifier (OPA). A cw laser provides an OPA seed input at a wavelength between 2000 nm and 2200 nm. The idler output of the OPA having difference frequency wavelength between 2000 nm and 2100 nm is further amplified by a crystal amplifier. The fiberoptic amplifier can include Ytterbium-doped fiberoptic. The crystal amplifier can include a Ho:YAG, Ho:YLF, Ho:LuAG, and/or a Ho:Lu2O3 crystal.
