Quenching treatment for improvement of nonlinear optical response time in high-χ(3) CuCl-doped glasses

Quenching treatments were performed on CuCl microcrystallite-doped glasses prepared by a melting method. Radiative decay time measurement and chi((3)) measurement for the quenched glasses were performed using ps and ns laser. The glasses showed that the radiative decay time were shortened by one order of magnitude without a decrease of third-order nonlinear susceptibility chi((3)) after the quenching treatment from above 300 degrees C, The distorted structure of CuCl microcrystallites quenched from high temperature was considered to be most effective for the shortening of the lifetime of Z(3) exciton.
