摘要：

The quasi three level 912 nm continuous wave laser emission under directed diode laser pumping at 880 nm into emitting level F-1(3/2) of Nd:GdVO4 have been demonstrated. An end pumped Nd:GdVO4 crystal yielding 8.1 W of output power of 13.9 W of absorbed pump power. The slope efficiency with respect to the absorbed pump power was 0.679. To the best of our knowledge this is the first demonstration of such a laser system. Comparative results obtained for the pump with diode laser at 808 nm, into the highly-obsorbing F-4(5/2) level are given in order to prove the advantages of the 880 nm wavelength pumping.
