The idea of wavefront recording and reconstruction, known today as holography, was formulated by Gabor 1. His proof-of-principle experiment was done with the light of a high pressure mercury lamp; it ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

Shimadzu diffraction gratings are used in analytical instruments for research in the life sciences, chemistry, environmental monitoring, as well as synchrotron radiation and optical communications ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

At LASER COMPONENTS we offer a wide range of diffraction gratings that can be used in a variety of different applications including instrumental analysis, astronomical applications, and in laser ...

Inprentus continues to serve critical global customers on 5 continents. Inprentus was founded in 2012 by University of Illinois Physics Professor Peter Abbamonte to commercialize a novel method for ...
