The efficiency and output of the resonantly fiber-laser-pumped Er: AYG laser at 1645 nm using 0.25% doped crystal out-performed the 0.5% doped crystal. in addition to the reported decrease in efficiency because of cooperative up conversion, a significant loss of laser output during Q-switched operation was observed and identified as two-photon absorption. This is deleterious in the short-pulse, high-intensity operational regime.
