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 ...

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 ...

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

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 ...

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 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 ...
