Latest Patents

Duchesne holds a patent for a "Digital laser pulse shaping module and system." This invention provides a digital pulse shaping module for controlling a pulsed laser oscillator according to a digital input waveform. The module includes a clock generator that generates a plurality of phase-related clock signals and a shape generator that outputs a digital shape signal corresponding to the digital input waveform in Double Data Rate in response to the clock signals. A Digital-to-Analog Converter (DAC) converts the digital shape into an analog shape signal. This analog shape signal can be used to control the current source of a laser seed source or modulators in the laser oscillator, shaping a seed light signal. Additionally, the pulse shaping module may output a gate control signal with a predetermined timing relationship with respect to the digital shape signal.
