Scientists can now snap ultra-powerful laser pulses in one shot. RAVEN reveals distortions instantly, unlocking breakthroughs ...

We propose a vanadate crystal-based composite gain medium consisting of Tm3+ and Ho3+ ion-doped sections, which facilitates the direct use of common 800 nm diode lasers for a miniature 2.1 μm laser ...

I had already set up OctoPrint on a Raspberry Pi for one of my 3D printers. After some tweaking and research, I realized that ...

GaN-based laser diodes (LDs) with different barrier layers are investigated by using simulation and experimental methods. it is found that the absorption loss always decreases with the increasing ...

Abstract: Chaotic laser with a flat power spectrum up to 32.3 GHz has been generated by using a dual-wavelength optically injected Fabry–Pérot laser diode with optical feedback. The Fabry–Pérot laser ...

We're now living in times when a YouTuber is able to build what is apparently the world's strongest handheld laser. The device is powerful enough to melt titanium, fracture diamond, weld razor ...

The laser beams, Detroit police told the Free Press in an email, seemed to come from the Canadian side of the Detroit River and were directed at the department's air support unit.
