✦ Synopsis
We report a simple and novel scheme for continuous, single frequency scanning of a commercial F-center laser without any computer interfacing. The scheme utilizes galvo tuning of the cavity length with intracavity CaF, Brewster plates with servo loop control of the intracavity etalon. This permits continuous tuning of the F-center frequency over 0.8 cm-' under complete manual control, as well as arbitrarily long, concatenated scans, and trivial interfacing to a data acquisition system. This scanning spectrometer operation is demonstrated on direct absorption of atomic bromine.
