Method of and device for stabilization of the emission wavelength of a laser.

摘要

The method and the device obtain stabilization by locking the emission wave- length of the laser (1) to an absorption line of a gas. The radiation emitted by the laser (1) is guided through the environment (7) containing the gas to the detector (8) along an optical waveguide (6) giving rise to an evanescent field that propagates outside the waveguide (Figure 1).
