ABSTRACT:
A harmonic amplifier for a laser beam amplifies a harmonic frequency of the beam. The amplifier generates a series of electric fields across the beam, successive fields being directed oppositely. The spacing between the fields is related to the speed of propagation so as to amplify a particular harmonic. Typically this will be the second harmonic so that the amplifier acts as a frequency doubler. The fields can be provided by an array 6 of electrode pairs positioned on opposite sides of the beam 2 with a voltage generator 8 connected across the sets in alternately opposite sequence.
