Paper Abstract

The results of frequency locking experiments with coupled ruby lasers are presented. The single axial mode characteristics of an individual saturable dye-switched laser can be understood without requiring spectroscopic hole burning in the dye. For coupled lasers in which frequency locking is observed, the existence of a spectroscopic hole seems necessary to explain the experimental results. The widths of the holes are inferred to be about 0.10 cm-1 using pyridine and 0.04 cm-1 using cyclohexanol as solvents. A relatively slow time dependent perturbation of the dye by thermal density fluctuations in the solvent yields a fluctuation in the transition energy of about 0.12 cm-1, which is in qualitative agreement with the inferred widths.
