Abstract
A yb laser at 976 nm is a three level system. By placing Sm in the core (to reduce stimulated emission above 1,000 nm) and Yb in a surrounding ring, a more efficient laser at 976 nm can be obtained. This will be Q-switched to serve as the first stage of a pulse source in a MOPA configuration. The second stage will be a HOM fiber designed to amplify the pulses from the first stage. With a HOM fiber design, it will be possible to obtain pules in the 20 mJ range at a repitition rate of 1 kHz with nanosecond pulses. This output will be frequency doubled with a nonlinear crysta.
