Stimulated Raman scattering at kHz pulse repetition rates

Abstract
Stimulated Raman scattering (SRS) has been achieved at kHz pulse repetition rates. The Raman oscillator consists of a lithium iodate crystal placed inside a Nd:YAlO3 laser, with feedback provided at the Stokes wavelengths by mirrors surrounding the crystal. First and second Stokes outputs at 1.18 and 1.31 μm, respectively, were generated from oblique longitudinal‐optic (LO) phonons in the lithium iodate. These results open the possibility of realizing substantial average output powers from Raman oscillators for the first time.
