195 W injection-locked single-frequency laser system

In this paper a high-power ring resonator is presented with four end-pumped laser heads injection-locked via an intermediate 12 W laser to a single frequency NPRO. With this setup a linearly polarized, single-frequency, fundamental mode output power of 195 W was demonstrated. This is the first time that injection-locking for a high power laser was highest injection-locked single-frequency output power.
