    Abstract: A circuit includes a first photo detector and a second photo detector to receive a first and second light input signal, respectfully, to generate a first current output signal and second current output signal respectively in response to the respective light input signals. A current multiplier stage receives the second current output signal from the second photo detector to generate a multiplied current output signal that is greater than the magnitude of the second current output signal. A differential multiplier having a first current path receives a portion of the multiplied current output signal and a second current path that receives another portion of the multiplied current output signal. The first current path is in series with the first current output signal to facilitate balancing of currents between the first current output signal of the first photo detector and the second current output signal of the second photo detector.

    Abstract: In a laser-produced plasma (LPP) extreme ultraviolet (EUV) system, laser pulses are used to produce EUV light. To determine the energy of individual laser pulses, a photoelectromagnetic (PEM) detector is calibrated to a power meter using a calibration coefficient. When measuring a unitary laser beam comprising pulses of a single wavelength, the calibration coefficient is calculated based on a burst of the pulses. A combined laser beam has main pulses of a first wavelength alternating with pre-pulses pulses of a second wavelength. To calculate the energy of the main pulses in the combined laser beam, the calibration coefficient calculated for a unitary laser beam of the main pulses is used. To calculate the energy of the pre-pulses in the combined laser beam, a new calibration coefficient is calculated. When the calculated energy values drift beyond a pre-defined threshold, the calibration coefficients are recalculated.
