In the past three decades, the race to achieve petawatt (PW) high peak power based on the techniques of chirped pulse amplification (CPA) 1 and optical parametric CPA (OPCPA) 2 has been underway, and ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

Free-space optical communication (FSOC) enables high-speed, secure, and scalable data transmission, with great potential for space–ground networks. However, existing FSOC systems predominantly employ ...

We’ve seen just about every possible way to make a clock here at Hackaday over the years. So it’s rare to have a first, but here we are with [Twisted & Tinned], who’s made a novel clock with a ...

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 ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for ...

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 ...

This review analyzes III-V monolithic integrated tunable lasers, highlighting design principles, performance trade-offs, 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 ...

As stated in the article titled ‘An Introduction to a Spectrometer: The Slit’, a spectrometer is an imaging system that maps a plurality of monochromatic images of the entrance slit onto the detector ...
