Christmas lights on the outside of your house might look awesome, but they really aren't that much fun to hang up. This year, we are using something different—lasers. Yes, you can now add Christmas ...

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 ...

Light diffraction and interference are investigated. Unit 6 Segment H: Light: Diffraction and Interference Light diffraction and interference are investigated as we observe light going through single ...

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 variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...
