Latest Patents
One of Qize Shu's latest patents is titled "Pulsed laser with intracavity frequency conversion aided by extra-cavity frequency conversion." This innovative pulsed third-harmonic laser system includes a pulsed laser, an extra-cavity nonlinear crystal, and an intracavity nonlinear crystal. The system generates fundamental laser pulses and couples out a portion of each pulse to undergo second-harmonic generation in the extra-cavity nonlinear crystal. The resulting second-harmonic laser pulses are directed back into the laser resonator, mixing with the fundamental laser pulses in the intracavity nonlinear crystal to generate third-harmonic laser pulses. This design maintains a non-zero output coupling efficiency regardless of the efficiency of the second-harmonic generation stage, while benefiting from the intracavity power of the fundamental laser pulses.
Another notable patent is the "Laser wavelength stabilization apparatus." This invention features a wavelength sensor for stabilizing the wavelength of a laser beam. It includes an etalon placed in the laser beam and tilted with respect to it. Reflected beams from the etalon create an interference pattern on a segmented photodetector with two segments. The output signals from these segments are used to derive an error signal for a closed control loop, effectively stabilizing the wavelength of the laser.
