A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but ...

High-power direct-diode lasers have emerged as a competitive option for applications like cladding, welding and heat treating. Stuart Woods of Coherent explains why the basic construction and ...

When we think about the onward march of automotive technology, headlights aren’t usually the first thing that come to mind. Engines, fuel efficiency, and the switch to electric power are all more ...

Diode-pumped alkali lasers (DPALs) represent a significant advance in laser technology, merging the efficiency of semiconductor pumping with the unique properties of alkali vapour media. By utilising ...

Researchers from Japan have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications ...

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 cutting and engraving technologies have become essential tools across a wide variety of different industries, from manufacturing, art and small businesses. These technologies use laser beams to ...

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 ...

Fifteen years ago, touring with lasers meant hauling argon gas tanks and cooling systems that filled entire trucks. Crews ...
