摘要：

The strong confinement of light in planar-optical waveguides has been used to measure the two-photon absorption coefficient, beta, in 4-butoxycarbonylmethylurethane polydiacetylene (4BCMU) thin films. Prisms were used to couple the 30-60 ps pulses (up to 10-mu-J) from a mode-locked YAG laser (lambda = 1.06-mu-m) into the thin-film waveguides. A simple analytical theory is compared with the experimental results to give a value of beta almost-equal-to 4 X 10(-3) cm/MW.
