摘要：
A method and apparatus for stabilizing the wavelength in a laser. The apparatus includes a first and second etalon for fine and rough tuning, respectively, of a laser oscillator. The output power and wavelength of the laser beam, for example, can be used to adjust these etalons to provide a constant output power and to counteract the change in etalon characteristics due to heat.
