Paper Abstract

The pyroelectric effect exhibited by two nonlinear optical materials is used to measure the residual absorption in their transparency window. The polarization behavior of potassium titanyl phosphate KTiOPO4 and thallium arsenic selenide Tl3AlSe3 are first described to determine the value of their pyroelectric coefficient. The pyrospectroscopic technique is then applied for absorption coefficient measurements at discrete laser wavelengths with a relative uncertainty estimated around 10 percent.
