Investigation of Photothermal Effects in Guest-Host Liquid Crystals based on Heat Conduction Analysis

Abstract

We investigated of photothermal effects in guest-host liquid crystals (GHLCs) by use of the heat conduction analysis. Photo-thermal effects were occurred by heat that generated by irradiating the GHLCs with a laser beam. The phase of the laser beam was modulated by the photothermal effects and the laser beam was defocused due to the phase modulation. Refractiveindex change(δn) due to the photothermal effects was estimated from the Kirchhoffs diffraction analysis for beam profile and heat conduction analysis.
