Abstract: | We demonstrated a diode-end-pumped continuous-wave 914 nm laser using a novel grown-together YVO4/Nd:YVO4 crystal for the first time. A maximum output power at 914 nm of 7.5 W with an optical-optical efficiency of 16.3% and a slope
efficiency of 24.3% was obtained when the incident pump power was 46.2 W. The beam quality factor M
2 was 3.2 at the output power of 6.0 W. The quality and specification of the grown-together composite YVO4/Nd:YVO4 crystal should be improved. Meanwhile, energy-transfer upconversion spectrum of the composite YVO4/Nd:YVO4 crystal laser was also investigated. |
