Fiber optical parametric chirped-pulse amplification (FOPCPA)

A fiber optical parametric chirped-pulse amplification device, comprising:

• a pump laser beam generator to produce a chirped pump beam at a pump wavelength;
• a signal laser beam generator to produce a signal laser beam at a signal wavelength different from the pump wavelength;
• one or more pulse stretchers operable to temporally stretch pulse durations of at least one of the signal laser beam and the pump laser beam to produce output laser light;
• a fiber optical parametric amplifier (OPA) including a fiber medium and coupled to the one or more pulse stretchers to receive the output laser light from the one or more pulse stretchers to cause a nonlinear parametric interaction in the fiber medium due to presence of laser light at the pump wavelength and laser light at the signal wavelength to produce an output signal laser beam at the signal wavelength, an output idler laser beam at an idler wavelength, and an output pump laser beam at the pump wavelength;
• and
• a pulse compressor operable to shorten a pulse duration of one or both of the output signal laser beam and the output idler laser beam.
