Residual stress birefringence in crystal will affect frequency conversion efficiency and beam quality. In this paper the distribution characteristics of inherent stress birefringence in crystal is analyzed, through delicate adjustment the optical axis is oriented and qualitative results obtained for KDP crystals are presented and discussed by imaging digital stress measurement instrument, and the stress gradient distribution is calculated, also the effect of deviation from optical axis on the measured stress distribution results is discussed.
