Abstrakt: | Low-threshold operation of a 2.09-μm holmium laser, excited by nonradiative energy transfer from trivalent iron, has been demonstrated. With a 1.45-mm-thick crystal of Fe,Ho:YGG at 77 K, absorbed power thresholds between 5 and 8 mW were observed as the pump wavelength was continuously tuned from 0.92 to 0.97 μm. |
