Continuous-wave 1934 nm laser with 120 mW output power

This is the authors' abstract. We don't add key points for this paper.

This Letter describes an all-solid-state continuous-wave, deep-ultraviolet coherent source that generates more than 100 mW of output power at 193.4 nm. The source is based on nonlinear frequency conversion of three single-frequency infrared fiber laser master-oscillator power-amplifier (MOPA) light sources.
