Abstract
We report what we believe to be the first demonstration of a room-temperature, continuous-wave Cr4+: Y3Al 5O12 (Cr4+: YAG) double-clad crystal fiber laser grown by the codrawing laser heated pedestal growth method. The threshold is below 100 mW, which is a factor of 4 lower than previously reported Cr 4+-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 0.08 dB/cm and the high crystallinity of the core. © 2008 Optical Society of America.
