ABSTRACT:
A fiber laser system includes a predominately single spatial mode, linearly polarized master oscillator providing a set of optical pulses and a polarization-maintaining optical isolator optically coupled to the master oscillator. The fiber laser system also includes a fiber amplifier optically coupled to the optical isolator and including a power amplifier comprising a double clad gain fiber, one or more pump lasers, and a pump coupler. The fiber laser system further includes a pulse compression stage optically coupled to the fiber amplifier. The pulse compression stage includes a volume holographic phase grating. Moreover, the fiber laser system includes a nonlinear frequency conversion stage optically coupled to the pulse compression stage.
