A breakthrough to achieve high-power THz sources is needed. This review covers recent advancements in laser-based THz generation, specifically using ultrafast lasers.
The present disclosure relates to a system for laser processing of a ceramic electrolyte material. The system may include a controller, a laser responsive to the controller for generating a beam, and a beam forming subsystem. The beam forming subsystem controls a parameter of the beam generated by the laser. The beam forming subsystem further controls the beam to provide a laser fluence sufficient to produce densification of the ceramic electrolyte material.
An optical inspection system for detecting sub-micron features on a sample component. The system may have a controller, a camera responsive to the controller for capturing images, an objective lens able to capture submicron scale features on the sample component, and a pulsed light source. The pulsed light source may be used to generate light pulses. The camera may be controlled to acquire images, using the objective lens, only while the pulsed light source is providing light pulses illuminating a portion of the sample component. Relative movement between the sample component and the objective lens is provided to enable at least one of a desired subportion or an entirety of the sample component to be scanned with the camera.
