Optical Dispersion Properties of Tricyanovinylaniline Polymer Thin Films for Ultrashort Optical Pulse Diagnostics

Abstract

We have investigated a series of tricyanovinylaniline (TCV) polymer thin films for their use in ultrashort optical pulse (USP) diagnostics of femto second Ti:Sapphire lasers. These thin films are ideally suited for USP diagnostics since they eliminate the angle tuning associated with birefringent phase-matched crystals, minimize pulse distortion introduced by group velocity dispersion, and exhibit excellent photochemical stability. The linear optical dispersion of these polymers can be tailored over a wide range for efficient and distortionless frequency conversion. Coherence lengths between 420 nm and 54 microns at a wavelength λ = 800 nm have been found for the two extreme cases of dispersion in these materials. Film thicknesses of at least two microns are tolerable without introducing any significant pulse distortion at the same wavelength (λ = 800 nm).
