Abstract
Yb double clad lasers are the "work horse" of high power systems. By codoping with Sm to quench stimulated emission at 1,070 nm (4 level system), Yb/Sm can be forced to lase efficiently at 980 nm. By further using HOM (Higher Order Mode) fiber design, greater energy storage/length can be achieved, and the shorter length also favors 980 nm radiation. Frequency doubling the q-switched output from such a system with periodically polled lithium niobate, all of the required design criteria desired by the Navy can be met with this new concept.
