High-power continuous-wave laser operation was demonstrated with Yb : K Lu ( W O 4 ) 2 crystals cut along the N p , N m , and N g principal optical axes, achieving a nearly equal slope efficiency of 79%–80% in the absence of thermal effects. The N g -cut crystal proved to be the most advantageous for power scaling as well as efficient pumping. A maximum output power of 11.0 W was produced from a 2 mm thick uncoated N g -cut crystal in a 7 mm long plano–concave resonator end pumped by a fiber-coupled diode; the corresponding optical-to-optical efficiency was 68%.
