Abstract
Two-photon absorption and two-photon excitation fluorescence of salicylaldehyde azine 1 crystals were investigated. It was observed an intense visible fluorescence when this material was excited with a laser tuned at the near infrared region. Varying the laser intensity we characterized this phenomenon as a simultaneous two-photon laser absorption process. Using open aperture Z-scan measurements we characterized this two-photon absorption phenomenon and measured the value of the two-photon absorption cross-section of this molecule to be equal to 87GM. Our results indicate that this is a promising organic material aiming nonlinear photonics applications.
