250 W single crystal fiber Yb:YAG laser

March 30, 2012

More than 250 W of output power out of an Yb:YAG single crystal fiber at an optical efficiency of 44% have been demonstrated at the IFSW in collaboration with the LCFIO and Fibercryst. The power in cw operation exceeds previously reported results by more than a factor of 4. These results confirm the applicability of single crystal fibers for highly efficient power amplifiers.
