Abstract
We report the demonstration of high power (660 mW) CW operation of a diode- pumped mid-IR Er fiber laser. This was achieved by using efficient depopula tion of the lower laser level via enhanced cross-relaxation between Er ions and energy transfer to Pr ions (at doping densities much higher than those used previously in Er:ZBLAN), along with optimal pumping of such lasers vi a custom-designed double-clad fluoride fibers.
