Using High-Speed Photodetectors for Pulsed-Laser Measurements

Our time-domain optimized high-speed detectors (Models 1444, 1454, and 1024) are commonly used for measuring the pulse shape of short-pulsed lasers or for generating an optical trigger …

Technical Notes

Nonclassical Concave Grating Imaging

For nonclassical groove patterns, the aberration coefficients Fij must be generalized to account for the image-modifying effects of the variations in curvature and spacing of the grooves, …
