Latest Patents
One of his latest patents is the High Power Solid State Laser Modulator. This invention features a multi-stage magnetic modulator that generates a pulse train of ±40 kV electrical pulses at a repetition rate of 5-7 kHz for a metal vapor laser. The design incorporates a fractional turn transformer that steps up the voltage by a factor of 80 to 1, utilizing magnetic pulse compression to minimize the pulse width. The transformer is constructed using a rod and plate stack type to achieve a high packing factor. Additionally, the pulses are regulated by an SCR stack, where multiple SCRs are connected in parallel, each linked to a saturable inductor wound on the same core of magnetic material, enhancing power handling capabilities.
Another notable patent is the Jitter Compensation Circuit. This invention samples the instantaneous Vco signal on a charging capacitor and captures the charge voltage on capacitor Co just before its discharge into the first stage of the magnetic modulator. The captured signal is processed through an averaging circuit with a long time constant and is applied to a differential amplifier. The differential amplifier generates an error signal by
