Abstract

We report what we believe to be the first demonstration of a room-temperature, continuous-wave Cr4+:Y3Al5O12 (Cr4+:YAG) double-clad crystal fiber laser grown by the codrawing laser heated pedestal growth method. The threshold is below 100mW, which is a factor of 4 lower than previously reported Cr4+-doped lasers. A slope efficiency of 6.9% was obtained, and is in good agreement with the numerical simulation. In additional to small core diameter, the low-threshold lasing is made possible by the low propagation loss of 0.08dBcm and the high crystallinity of the core.
