Latest Patents
John J McDonald holds a patent for a pulsed laser system. This system is capable of operating in multiple modes to deliver bursts of laser pulses to a target. The pulse width of these laser pulses is automatically controlled based on the selected mode. A special calibration procedure enables the system to determine the pulse width and pulse repetition rate when the laser produces a predetermined power output level, as measured by a power meter at the target site. The calibrated pulse width and pulse repetition rate allow for precise delivery of laser pulses for specific treatment bursts. Additionally, the system includes means for determining the energy delivered to the target during each treatment burst. A potentiometer linked to a laser spot size control lens assembly provides a signal proportional to the spot size. This information, combined with the energy delivered, allows for the calculation of energy density. The system also features a special REPEAT mode, which enables the operator to automatically repeat bursts of laser pulses at preselected intervals while the foot pedal is depressed.
