Abstract
One or more birefringent plates are placed within the optical cavity of an optical oscillator such as a dye laser. Each of the plates is positioned at an angle, such as Brewster's angle with respect to the light reflected within the optical cavity of the optical resonator. The output wavelength from the optical resonator is tuned, or its bandwidth narrowed, by rotating the birefringent plates while maintaining the plates at the same angle.
