Abstract
The thermal dependences of the principal refractive indices of lithium triborate (LBO) have been measured over an extended temperature range of 20–200 °C with a Michelson interferometer. The data obtained are critically evaluated by prediction of the temperature dependences of phase matching and the temperature bandwidth of LBO in a wide range of circumstances (which include optical parametric oscillation, second-harmonic generation, and sum-frequency-mixing generation), and close agreement with experimental observation is obtained in most cases.
