Stabilized lasers and applications
Abstract
The paper discusses the stabilization of gas lasers by the technique of saturated absorption, accomplished in the servo-controlled laser by means of an internal molecular absorption cell. A heterodyne technique using silicon diodes and high frequency metal-metal point contact diodes for the frequency measurement of stabilized lasers is described. Four areas of application of stabilized lasers are discussed: (1) measurement of fundamental constants (e.g., the speed of light), (2) redefinition of the meter, (3) ultrahigh (10 to the 10) resolution spectroscopy and (4) broadband seismographs.
