Abstract
The optical nonlinearity of a mode-locking dye (Kodak 9740) under picosecond excitation at 532 nm, is studied using the Z-scan technique. Theoretical fits to the data give a value of 3.2 cm/GW for the two-photon absorption coefficient (β) and -2.1×10-5 cm2/GW for the real part (γ) of the nonlinearity. In addition, we demonstrate optical limiting using two-photon absorption as well as self-defocusing.
