Abstract
We demonstrate experimentally an all-fiber nonlinear optical modulator which can find application for high power (greater than 20 W) single-mode fiber lasers. Stimulated Raman scattering is used to transfer the amplitude modulation from a low-power signal beam at the Stokes frequency onto a high-power beam. Efficient modulation of 1064 nm pump radiation by 100 ps Stokes pulses is demonstrated in a highly Ge-doped fiber.Keywords
