Electronic Tuning of a Dye Laser Using the Acousto-Optic Filter

Abstract

A dye laser which is electronically tunable over 780 Å has been obtained by inserting a CaMoO4 acousto-optic filter into the dye-laser cavity. A filter half-power linewidth of 6.8 Å yields a laser linewidth of 1.35 Å. Oscillation at two simultaneous independently tunable wavelengths and electronically variable output coupling has been observed.
