The variant of refractive indices with temperature is an essential crystal parameter in nonlinear optics. it is well known that the wavelength at which 90° phase-matched 2nd-harmonic era happens depends on temperature. the variation of this wavelength with temperature can be predicted with a…

It’s well known that the DKDP crystal is very easy to be damaged by humidity, especially in  environment with high temperature. So ordinary DKDP Pockels cells can not be used in high temperature and high humidity environment, or their service life is very short. After more than two years of…
