| Abstract: | This paper,for the first time in China,demonstrates frequency-quadrupling in an LD-pumped solid-state laser using potassium titanyl phosphate (KTP) and beta barium borate (β-BBO) With common planar-planar cavity,the slope efficiency of one-end-pumping lasing of Nd:YVO4 is as high as 55.68% An intra-cavity frequency doubled green laser with Ⅱ-type phase-matched of KTP has been experimentally demonstrated The highest green laser output power is 1.35W,obtained at 11.85W of pump power,corresponding to an optical-optical conversion of 11.4% Resonance effects in the ring resonant external cavity of the fundamental and of the second harmonic are derived Using a β-BBO crystal the ultra-violet laser is generated. |
