Abstract: A method for generating ultrawideband pulsed microwave signals from optical field ionization of a gas with an ultrashort laser pulse, where the amplitude and frequency of the signals can be controlled via the characteristics of the laser pulse and/or the gas. The center frequency of the spectrum of the microwave signal can be controlled by changing the laser pulse energy. The amplitude of the microwave signal can be controlled by changing the wavelength of the laser pulses. The amplitude and frequency of the microwave signal can be tuned by controlling the pressure of the gas medium. The location at which the microwave signal is generated can be controlled by controlling the location at which the laser pulse creates a plasma. Interference among microwave signals resulting from multiple laser-produced plasmas can be used to construct an ultrawideband microwave signal having a predetermined amplitude and frequency.
