Abstract : The R sub 1 absorption doublet in pink ruby has been studied near 90K, using alpha-polarized incident radiation with both coherent and incoherent sources. A 2-inch ruby laser was used as the coherent source. Frequency scanning was accomplished by varying the relative temperatures of source and sample. Incoherent light measurements were made with a one-meter Ebert spectrometer using a zirconium-arc source. Careful measurements were made of the wavelength separation of the R sub 1(1/2) and R sub 1(3/2) components, in the laser source, as well as the separation of the longitudinal modes in each component. The component spacing was found to be 0.3829 plus or minus .0004/cm and the mode separation was 0.0397/cm. The maximum values of absorption coefficient, using white light, were 10.7/cm for R sub 1(3/2) and 8.8/cm for R sub 1(1/2). Absorption coefficients corresponding to coincidence of the laser output with the centers of the corresponding lines in the sample varied between 9 and 3/cm depending on the intensity and degree of plane-polarization of the beam.
