Spectroscopic Frequency Calibration of Tunable Dye Lasers

Volume 38, Number 2 (April 1984) Page 212-214

Hamer, Cheryl A.; Spoonhower, John P.


A simple, inexpensive technique for optogalvanic frequency calibration of tunable dye lasers is presented. Its feasibility is demonstrated in the acquisition of the photoluminescence excitation (PLE) spectrum of a weakly emitting species. This experiment reveals a number of problems inherent in the use of tunable dye lasers in low-light-intensity investigations, for example, in obtaining PLE spectra or in obtaining resonance Raman enhancement profiles.
