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 ...

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, ...

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 ...

Ultrashort laser pulses - that are shorter than a millionth of a millionth of a second -have transformed fundamental science, engineering and ...

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 ...
