Abstract : The frequency of a laser beam can be changed by directing the laser beam through a crystal that has paraelectric and ferroelectric states, above and below a Curie transition temperature, respectively. The crystal is maintained at a constant temperature slightly above its Curie transition temperature when no change in the frequency of the laser beam is desired; and a voltage is applied across the crystal to drive it from its paraelectric into its ferroelectric state when a relatively large change in the frequency of the laser beam is desired.
