Abstract
A new calorimetric interferometry using a pulsed high power Nd-glass laser was developed to determine small absorption coefficients of the order of 10−3 cm−1 or less at the wavelength of 1.06 μm. The absorption coefficients of the liquid specimens, C6H6, C6H5Cl, 0-C6H4Cl2, and 1,2,4-C6H3Cl3, were determined by the fast acquisition of an interferogram, accurate microcalorimetry, and the measurement of the laser beam radius.Keywords
