Abstract
A time modulated source of frequency doubled laser radiation is described in which a non-linear crystal part of a stripline electrical circuit is mounted within a laser cavity so that the laser beam at a fundamental frequency impinges on and propagates through the non-linear crystal. A high bandwidth electrical data signal is coupled into the stripline electrical circuit to produce an electric field across the non-linear crystal so that an output beam is produced at a wavelength corresponding to the second harmonic of the fundamental frequency which represents a frequency doubled output beam modulated in accordance with the high bandwidth data signal, an alternate embodiment for producing the time modulated source of frequency doubled laser radiation has the non-linear crystal placed in a resonant microwave cavity. A high bandwidth electrical signal modulates the intensity of the microwave electric field across the non-linear crystal so that an output beam is produced at a wavelength corresponding to the second harmonic of the fundamental frequency which represents a frequency doubled output beam modulated in accordance with the high bandwidth data signal.
