Abstract
A tipping Brewster plate, used for fine tuning a tunable ring laser, such as a dye laser, is located close to a flat mirror comprising one of the optical elements of the ring optical resonator, so that both the incident and reflected beam from the flat mirror pass through the tipping Brewster plate. When the ring laser is tuned by tipping the Brewster plate, no lateral displacement of the ring laser beam takes place.
