Abstract
The optical characteristics of KDP/DKDP crystals, including thermal absorption and nonlinear absorption, were investigated through thermal lens method and Z-scan method. It is found that the thermal absorption in KDP crystal behaves anisotropy at 355nm and 532nm and nonlinear absorption anisotropy in KDP/DKDP crystals is also found at 520nm. For KDP and DKDP samples, the thermal absorption coefficient of crystals with different orientations is slightly different. The four-photon absorption coefficient γ of z-cut KDP sample is larger than that of other orientations. The relationship of nonlinear absorption coefficient γ is z<II<I for KDP sample, while II≈z for DKDP sample.
