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, ...
Reflective ruled diffraction grating is a kind of optical glass substrate composed of dense, equidistant parallel lines, and the surface is coated with aluminized, multi-layer dielectric or other ...
One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...
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 ...
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.
