Abstract: A surface inspection system can be provided with a laser spot size or a laser line width that is selectable based on a measurable aspect of the objects under test that project upward or downward from a surface under test. The larger laser spot size or line width can be selected to cover a larger area of the surface under test at a time, which can increase scanning speed over the surface under test and enhance system measurement throughput.

Abstract: A power converter, a control method for the power converter, and an energy storage system. When high voltage ride-through occurs, a bus voltage is increased from a first voltage to a second voltage, and a direct current-to-direct current converter circuit adjusts a maximum output power to a first power based on a control signal, and outputs a power within a range in which the power is less than or equal to the maximum output power. An external characteristic of the direct current-to-direct current converter circuit is changed to stabilize the bus voltage and avoid oscillation of the bus voltage. The first power is greater than a second power, and the second power is a maximum output power of the direct current-to-direct current converter circuit existing when there is no control signal and the bus voltage is the second voltage.

Abstract: The present disclosure discloses a miniaturized MOPA structure DPSSL (Diode Pumped Solid State Laser), which comprises a laser oscillator module and a laser amplifier module. The laser oscillator module consists of a seed laser and its collimating system, and the laser amplifier module consists of a laser pump module and a laser gain element. The seed laser with high beam quality is collimated by a collimation system, then input into the gain element; the pump laser is pumped into the gain element via end pump or side pump mode. The seed laser beam transmits into the gain medium and is reflected by the interface several times with the “Zigzag” path, which makes the seed laser fully gained and amplified, finally achieving high power and high beam quality laser output. In this present disclosure, the laser gain material is doped with different rare-earth ion concentrations and processed into different shapes.

Abstract: The present application provides a method and system for automated inspection of a microfabricated feature on a substrate. The disclosure utilizes manipulating laser polarization in combination with the excitation and emission process, in inspection applications. The application specifically discloses selecting the polarization of the laser light by adjusting a polarization manipulator or a quarter-waveplate and/or a half waveplate between the laser source and the substrate to impart polarization to the laser light. The polarization impacts using a polarization selected to improve fluorescence emission of certain features on a substrate. The selection can be made prior to run time or dynamically during the inspection tool runtime. If the polarization is not specifically selected, then the microfabricated features may not emit much fluorescence.

Abstract: A stent for aorta is formed by weaving at least two types of filaments having different diameters, such as a first filament and a second filament. The stent is configured to be at least partially compressible and extensible along the axial direction of the stent in a natural release state, wherein the first filament has a diameter of 20-150 ?m, and the second filament has a diameter of 150-800 ?m. When the stent is used in the treatment of aortic aneurysm and/or aortic dissection lesions, due to the axial compressibility and extensibility of the stent, low liquid permeability and strong radial support force are provided where needed in the aorta, and due to the axial stretchability thereof, the stent can be easily assembled to a delivery system having an appropriate diameter. Also provided are a stent kit comprising the stent and a stent delivery system.

Abstract: An intracavity frequency-doubling laser device includes a first mirror and a second mirror defining a resonance cavity, a gain media to produce a first lasing light in response to an external pump beam received from outside the cavity, a nonlinear frequency-doubling optical element to generate a second lasing light in response to the first lasing light, a birefringent waveplate to control phase properties of the first and second lasing lights, and a fused quartz element positioned at the exit of the resonance cavity. The second mirror is formed as a relatively thick film on the fused quartz and is controlled to create an output beam of the second lasing light with great accuracy. The four components within the resonance cavity are positioned back-to-back and held in place using an optical glue (forming a compact, miniaturized laser device).

An error property can be determined and removed from the raw centroid calculation results to generated refined centroid calculation results. A characteristic of the surface feature can be determined based on the centroid calculation results.

Abstract: Various examples described herein include various mechanisms, techniques, and methods to subtract collected signals caused by a periodic pattern formed on substrates to enable a higher level of defect detection on substrates. Signals detected by various types of metrology and substrate-inspection systems that are caused by periodic patterns on inspected substrates can be reduced or eliminated by, for example, a Fourier analysis of the detected signals. Both gray-scale value thresholds and area thresholds may be applied after the Fourier analysis of the image and are sufficient for defect detection on an image with a substantially-reduced number of false defects or no defects being present in a final image produced after processing. Other techniques and methods are also disclosed.
