Laser frequency stabilization to water vapour absorption lines using direct- and offset-locking techniques

Frequency stabilization is generally performed by using atomic or molecular absorption lines. However, it is sometimes necessary to lock a laser at a frequency located outside of any absorption peaks. In this case, an offset locking configuration is necessary, in which a so-called slave laser is locked at a given frequency difference with respect to a stabilized master laser.
