Abstract

Various efficient nonlinear frequency-conversion applications, such as second-harmonic generation and optical parametric oscillation, were demonstrated with potassium titanyl phosphate (KTiOPO₄, or KTP). This is mainly due to its high nonlinear optical coefficients, low optical loss, high optical damage threshold, wide acceptance angle and thermally stable phase-matching properties.³ In recent years, there has been renewal of interest in the electro-optic (E/O) applications of KTP, such as E/O modulators and Pockels cells.^1,5 We have already demonstrated an intracavity frequency-doubled and Q-switched Nd:YVO₄ miniature laser by a single KTP crystal.^1,2
