Imagine a star so dense that a teaspoon of its material would weigh as much as Mount Everest, spinning hundreds of times per ...

Do home hair removal lasers work? I tried two popular options, the Ulike Air 10 and Nood Flasher 2.0 for two months. Find out ...

The successful delivery of two high-tech tool containers to the 4th Battalion, 60th Air Defense Artillery Regiment may have ...

Conventional accelerators use oscillating electric fields to drive charged particles to relativistic speeds. The Large Hadron Collider at CERN, for example, uses radio-frequency oscillations to ...

Two-dimensional (2D) semiconductors, such as transition-metal dichalcogenides (TMDs), have attracted immense interest due to their excellent electronic and optical properties. The combination of ...

Here, an efficient dissipative soliton mode-locked fiber laser in the L-band using nonlinear polarization rotation technology is demonstrated. With a maximum pump power of 495.3 mW and polarization ...

Optical pulses are generated by passive and hybrid mode-locking of a long wavelength (1075-1085 nm) InGaAs-GaAs ridge waveguide laser grown by gas source molecular beam epitaxy. The devices are ...
