Abstract
A fiber laser system includes a master oscillator configured to generate linear polarized infrared laser radiation with wavelengths of 1015-1085 nm, pulses with durations of 100 ps to 10 ns, pulse train repetition rates of 1 kHz to 10 MHz, spectral bandwidth less than 0.5 nm, and a predominately single spatial mode and a polarization-maintaining optical isolator optically coupled to the master oscillator. The fiber laser system also includes a fiber amplifier system optically coupled to the optical isolator and including a power amplifier configured to amplify the laser radiation transmitted through the optical isolator. The power amplifier includes a polarization-maintaining, large-mode-area, multiple-clad Yb-doped gain fiber having a core, an inner cladding, and at least an outer cladding, one or more diode pump lasers emitting pump light of a nominal wavelength of 976 nm, and a pump coupler configured to couple the pump light into the gain fiber.
