The technology described in this document can be used to implement an optical device including a seed pump laser to produce pump seed laser pulses at a pump wavelength, a pulse stretcher operable to stretch a pulse duration of the pump seed laser pulses to produce stretched pump seed laser pulses, a pump fiber amplifier including one or more fiber gain media to receive the seed pump laser pulses to produce a pump laser beam of pump laser pulses, a signal laser to produce a signal laser beam at a signal wavelength different from the pump wavelength, an optical module coupled to combine the pump laser beam and the signal laser beam, and a fiber optical parametric amplifier (OPA) to cause a nonlinear parametric interaction in the nonlinear fiber medium to produce an output signal beam, an output idler laser beam at an idler wavelength, and an output pump beam.

Fiber optical parametric chirped-pulse amplification (FOPCPA)

This disclosed subject matter allows short pulses with high peak powers to be obtained from seed pulses generated by a gain-switched diode. The gain-switched diode provides a highly stable source for optical systems such as nonlinear microscopy. The disclosed system preserves the ability to generate pulses at arbitrary repetition rates, or even pulses on demand, which can help reduce sample damage in microscopy experiments or control deliberate damage in material processing.
