Title: Ultraviolet fiber laser system

Abstract: Laser master oscillator-power amplifier system for generating high pulse energy, high average power laser pulses in the ultraviolet 191.25-201.25 nm and 243-246.25 nm spectral ranges, and in the visible 450-537.5 nm spectral range with controllable pulse duration and pulse repetition rate employ a master oscillator seed laser operating in the infra-red spectral range, and a single series connected chain of hybrid fiber-bulk optical amplifiers coupled to a non-linear frequency conversion unit to convert the laser pulses to the ultraviolet and visible spectral ranges.
