Latest Patents

David Shen holds a patent for an "Excimer laser pulse analyzer and method." This invention focuses on a system and method for analyzing pulses from an excimer laser by measuring light energy rather than heat energy. The output of the laser is monitored with a photodetector, which provides electrical current pulses corresponding to the intensity of the light in individual laser pulses. The current pulses are integrated to yield voltages that correspond to the light energy of the laser pulses. These voltages are then converted to digital signals, which are accumulated during the exposure period to determine the total light energy of the pulses. Additionally, the light energy for a shorter interval is divided by the length of that interval to ascertain the average intensity of the pulses. Displays are provided for both the light energy and the intensity of the pulses, as well as the length of the exposure period.
