Yb3+CaF2 laser has been intensively explored in recent years. In Yb3+CaF2 continuous-wave (CW) laser, the highest output power of 10.2 W pumped by a laser diode(LD) of 64 W has been reported in 2008. The first demonstration of the highest output power of 14.5 W in a LD-pumped Yb, NaCaF2 CW laser is presented, under the conditions of an absorbed pump power of 18.2 W and a output coupler of 4%, which corresponds to a laser slope efficiency of 80%. The result shows that the novel Yb, NaCaF2 crystal is an excellent laser material for low-threshold and high-power lasers.
