摘要：
A comparative study of Nd:GdVO4 and Nd:YVO4 crystal lasers pumped by a fiber-coupled diode array has been conducted at the F-4(3/2)-I-4(9/2) transitions wavelengths of 912 nm and 914 nm, as well as when intracavity frequency-doubled to 456 nm and 457 nm. respectively. At the fundamental wavelength of 912 nm and second harmonic wavelength of 456 nM, Maximum output powers from the Nd:GdVO4 Crystal laser were 7.85 W and 4.6 W at a pump power of 29 W. All the results obtained from Nd:GdVO4 were superior to those of Nd:YVO4, indicating that Nd:GdVO4 is a more efficient laser crystal than Nd:YVO4 for laser operation on the F-4(3/2)-I-4(9/2) transitions.
