Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

Diode-pumped lasers, whether in disk, fiber, or YAG form, have enjoyed great success, but for materials processing applications in the real world, direct-diode systems are unequaled. That's the view ...

“Electrically-pumped lasing has proven difficult because metal contacts tend to quench molecular excitation energy,” researcher Thomas Klar told optics.org. “Our research shows that gold nanodiscs on ...

Ultrashort laser pulses - that are shorter than a millionth of a millionth of a second -have transformed fundamental science, engineering and medicine. Despite this, their ultrashort duration has made ...

A laser light beam passes between a loudspeaker-reflector array that creates a grating of air. The laser beam interacts with this grating and is deflected without contact. Using a novel method, beams ...

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 ...
