Laser beam quality and pointing measurement with an optical resonator.
We present a compact diagnostic breadboard that is based on an optical ring resonator for measuring beam quality and pointing of single-frequency continuous wave lasers at a wavelength of 1064 nm. To determine the beam quality of the coherent test beam, this optical resonator is used to perform a mode decomposition into Hermite-Gaussian modes. For our laser system, a power fraction in the funda...
متن کاملCalibration of Laser Beam Direction for Inner Diameter Measuring Device
The laser triangulation method is one of the most advanced methods for large inner diameter measurement. Our research group proposed a kind of inner diameter measuring device that is principally composed of three laser displacement sensors known to be fixed in the same plane measurement position. It is necessary to calibrate the direction of the laser beams that are emitted by laser displacemen...
متن کاملCCD imaging system for precision beam steering in laser communications
A CCD imaging system has been developed for precision laser beam pointing. The systcm contains a high frame rate CCD camera operated in windowing mode under command of an ernbeddcd processor. A ltiser pointing and tracking update rate of 2 KIIz has been achieved. Subject terms: CCD cameras, laser pointing, laser communications.
متن کاملLaser Beam Hazard for flight personnel
Lasers can produce a beam of light of such intensity that permanent damage to human tissue, in particular the retina of the eye, can be caused instantaneously, even at distances of over 10 km. At lower intensities, laser beams can seriously affect visual performance without causing physical damage to the eyes; causing transient damage or causing sensation and loss of focus. Laser illumination o...
متن کاملEffects of beam pointing instability on two-beam interferometric lithography
In a photolithographic system, the mask patterns are imaged through a set of lenses on a resist-coated wafer. The image of mask patterns physically can be viewed as the interference of the plane waves of the diffraction spectrum captured by the lens set incident on the wafer plane at a spectrum of angles. Two-beam interference fringe is the simplest format of the image. Consequently, two-beam i...
