Needless to say, we’re fascinated by LEDs, laser diodes, and other blinkies. Although we can get just about any light emitting thing, the data sheets aren’t always accurate or available. For his ...

An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

Laser is of prime importance in Optical memories, Fiber optic communications, Military applications, Surgical procedures, CD players, Printers etc. Various forms of lasers like Gallium Arsenide laser, ...

Belgian research lab Imec is claiming to have created a metal halide perovskite LED stack that emits 1,000x more light “than state-of-the-art OLEDs”, it said. With the assistance of an external laser, ...

In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, ...

Called RLD90QZW8, “original technology allows Rohm to reduce the temperature dependence of the laser wavelength to just Δ11.6nm – 0.10nm/°C”, said the company. “This makes it possible to narrow the ...

Before going into exterior lighting solutions for all things automotive, it's necessary for us to remember that – in the olden days of black and white everything – horse-drawn carriage lamps used ...

In 1962, 50 years ago today, Nick Holonyak Jr. and his team at GE invented the Light Emitting Diode. While LED lights are almost everywhere today — from bridges to headlights to keychain flashlights ...

Efficient 1.5 W CW and 9 mJ quasi-CW TEM00 mode operation of a compact diode-laser-pumped 2.94 µm Er:YAG laser Sheaumann has developed the first commercially available diode-laser-pumped continuously ...

Cutting grass with lasers works great in a test setup. (Credit: Allen Pan, YouTube) Wouldn’t it be cool if you could cut the grass with lasers? Everyone knows that lasers are basically magic, and if ...
