Abstract

Defects in nonlinear optical barium metaborate crystals (?- and ?-BBO) have been investigated by means of optical spectroscopy and thermal activation methods. Low-temperature absorption peaks have been observed in all samples. The dependence of these peaks upon crystalline phase and type of the flux used while growing is low. This fact indicates that intrinsic defects play the leading role in absorption.. It is shown that while growing BBO crystals by TSSG technique, defects, which form deep electron-type traps in the forbidden gap, are generated.
