Latest Patents
Francis J Cusack, Jr holds a patent for an "Apparatus and method for frequency modulating a waveguide laser." This patent describes a CO₂ waveguide laser frequency modulation (FM) system that applies Fourier series components of a triangular drive waveform selectively to the tuning PZT at one end of the waveguide and the FM PZT at the other end. This method achieves an improvement over traditional waveforms by applying the fundamental component to the tuning PZT and the odd harmonics to the FM PZT. The system utilizes frequency-separated drive signals that are applied in proper phase to the PZTs at each end of the waveguide through a waveform synthesizer, frequency splitter, and amplifiers. The waveform synthesizer includes a ROM containing digitized values of segments of the waveform amplitudes and a digital-to-analog converter for converting the digital ROM data to an analog signal. This innovative approach has the potential to significantly enhance the efficiency and effectiveness of waveguide laser systems.
