Abstract

The two-photon absorption cross-section for diphenylbutadiene heated to the isotropic liquid state has been measured using the Z-scan technique. In this experiment, the solid diphenylbutadiene was heated using a temperature controlled hot stage above its melting point. Z-scan measurements using 35ps laser pulses at 532nm were then carried out on molten diphenylbutadiene. The value of the two-photon absorption cross-section at 532nm was measured to be σ2 = (38±8) × 10−50cm4s/photon-molecule. This value corresponds well with the cross-section measured previously for diphenylbutadiene dissolved in chloroform using the degenerate four-wave mixing technique.
