Abstract
A pulse laser system utilized for communication transmits a modulated pulsed laser beam having a precise wavelength to match a receiver. An etalon is positioned in the resonant cavity of the laser and is adjustable to tune the laser. A continuous wave reference beam is provided and is compared with the laser output beam and if the wavelength's bear other than a predetermined relationship with respect to one another, a control signal is generated to adjust the etalon in the laser resonant cavity. In one embodiment another etalon is placed in the reference beam path as well as the laser beam path with the transmitted beams being detected in order to derive normalized proportionality factors relating to each beam so that a comparison of the proportionality factors may be made and utilized for control purposes.
