High-average-power Raman oscillator employing a shared-resonator configuration

Abstract

The performance of a high-repetition-rate (kHz) Raman oscillator is described. The oscillator employs a new configuration in which the Raman medium is located inside the pumping laser, and the Stokes outputs and pumping laser share the same resonator. The Raman oscillator consists of lithium iodate pumped by the 1.08-μm output of Nd : YAlO3. In separate experiments, we have generated 1.26 W of 1.18-μm first Stokes average output power and 550 mW of 1.31-μm second Stokes average power.
