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, ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

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, ...

The dual nature of light has long been a concern of scientists. It even led to the creation of the to the controversy between Albert Einstein and Niels Bohr on whether light can be observed ...

The exoskeleton of a tiny organism has been used as a diffraction grating by researchers in Vienna, who have carried out a molecular interferometry experiment using it. The team showed that a coherent ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...
