摘要
本文报道在国内首次实现的ＬＤ泵浦的四倍频连续紫外激光器的实验结果．首先研究了ＬＤ泵浦的Ｎｄ∶ＹＶＯ４激光器，在普通平－平腔结构下，得到斜效率５５．６８％，激光输出波长１０６４ｎｍ；利用ＫＴＰ作为倍频晶体，实现腔内倍频，在泵浦功率１１．８５Ｗ时得到绿光（５３２ｎｍ）输出１．３５Ｗ，光－光转换效率１１％；用ＢＢＯ晶体进行外腔谐振倍频。
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∶YVO 4 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
