Abstract
The use of feedback circuit in a laser device with a frequency selective element such as an etalon allows for the production of a substantially single longitudinal mode output indefinitely. The feedback circuitry is adapted to adjust the length of the laser cavity so that a longitudinal mode of the laser device is near transmission peak of the frequency selective element.
