Latest Patents

One of Alexander Weis's key patents is titled "Multi-stage MOPA with first-pulse suppression." This invention involves a solid-state MOPA that includes a mode-locked laser delivering a train of pulses. The system incorporates a fast electro-optic (E-O) shutter, which features polarization-rotating elements, polarizing beam-splitters, and a Pockels cell. The Pockels cell can be driven by high voltage (HV) pulses of both fixed long and short durations. The E-O shutter selects every Nth pulse from the input train and delivers these selected pulses to a multi-pass amplifier. The amplifier returns amplified seed-pulses to the E-O shutter, which then decides whether to reject or transmit the amplified pulses based on the duration of the HV-pulse. This innovative design allows for the suppression of first-pulse over-amplification and residual pulse leakage.
