Obviously the wavelength of a laser can’t be measured with a scale as large as that of a carpenter’s tape measure. At least not directly and that’s where a Compact Disc comes in. [Styropyro] uses a CD ...

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, ...

Laser tuning gratings are holographic gratings specially designed for wavelength tuning of lasers, such as dye lasers, Ti-sapphire, or external cavity diode lasers. The groove depth is optimised to ...

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 ...

At LASER COMPONENTS we offer a wide range of diffraction gratings that can be used in a variety of different applications including instrumental analysis, astronomical applications, and in laser ...

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 ...

In many industries, laser diffraction is used to perform routine particle size analysis. The power of laser diffraction is such that it has started to replace conventional techniques, such as sieving.

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 ...
