The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...

A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

A physicist has made the best ever p-n junction diode from a carbon nanotube. The current-voltage characteristics of the device exhibit an "ideality factor" of one, which is the maximum possible value ...

Diodes allow electricity to flow in only one direction, helping circuits work safely and correctly. This video explains how ...

Zener diodes behave differently from regular diodes by allowing current to flow in reverse at a specific voltage. This video explains how that property helps stabilize voltage in electronic circuits.

The first ever “optical” diodes made from the 2D material Ti 3 C 2 and fullerene (or carbon-60) retain their saturable absorption (or increased light transmission at higher laser powers) even after ...

A special type of diode made from a crystalline material whose layers are just three atoms thick has been successfully realized for the first time. The superior properties of such ultra-thin crystals ...
