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 112 and R sub 132 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 .0004cm and the mode separation was 0.0397cm. The maximum values of absorption coefficient, using white light, were 10.7cm for R sub 132 and 8.8cm for R sub 112. Absorption coefficients corresponding to coincidence of the laser output with the centers of the corresponding lines in the sample varied between 9 and 3cm depending on the intensity and degree of plane-polarization of the beam.
