摘　　要：当调ＱＮｄ∶ＹＡＧ脉冲激光通过ＬｉＩＯ３晶体时，由于晶体弱吸收激光而在其内激起应力波。在激光倍频时这种波得到增强，并随倍频的位相失配角变化。研究表明，这是因为激光倍频时部分１０６４μｍ的基频激光转换成０５３２μｍ的倍频光，并且ＬｉＩＯ３晶体吸收倍频光比吸收基频光更强。When Q switched Nd∶YAG laser radiation goes through a LiIO 3 crystal,the stress wave will be induced for the laser radiation weak absorption of the crystal.In SHG of 1064nm laser radiation,the stress wave are enhanced and vary with the variation of phase mismatching angle.In this process,there exist the 1064nm fundamental laser radiation and 532nm SHG radiation in LiIO 3 crystal,and the absorption to 532nm laser radiation is more serious than to 1064nm laser radiation.
