摘要：

Nonlinear optical properties of various glasses containing copper chloride nanocrystals have been studied at wavelengths of 532 and 1064 nm. It is established that the nonlinear optical response is manifested by the optical limiting of transmitted radiation and consists of two, low- and high-threshold parts. The low-threshold response is related to a self-defocusing of the radiation, while the high-threshold response is related to the phenomena of two-photon absorption, color center photogeneration, and thermal lens formation.
