Abstract
The dual laser wavelength Mach-Zehnder interferometric technique is used to study the thermal and optical properties of propylene carbonate (PC), which consider as important polar dielectric solvent for many laser dyes. Using Argon and He-Ne laser at wavelengths 514.5 and 632.8 nm as a light sources and Mach-Zehnder interferometer, many thermal and optical parameters are measured and many others are calculated. The experimental technique is used for measuring the refractive index and its gradient with temperature. Applying Cauchy,s equation the dispersion of PC can be studied. Using Murphy-Alpert,s equation the gradient of refractive index dn/dT as a function of wavelength and the density versus temperature are calculated and plotted. On the other hand, the constants A and B of Cauchy,s equation as a function of temperature were studied. Additionally, using Fresnel equations many optical properties such as transmittance and reflectance as a function of incident angle, temperature and wavelength are calculated and represented. This paper gives new data measured at high frequencies to be useful and available for all workers in the field of dye lasers (designers and researchers).
