摘要：

Bi2TeO5 is a new nonlinear optical material that exhibits the photorefractive effect including a long lived memory component. The nonlinear absorption properties of the material were investigated. With picosecond duration pulses, the two-photon absorption was found to be the predominant component of the nonlinear absorption. The two-photon absorption coefficient was measured to be 3.2-4.7 and 3.0-4.7 cm/GW for the [001] and [010] polarization directions, respectively. Contributions from free charge carrier absorption and excited state absorption were also observed using time delayed laser pulses.
