Laser diodes work on the same principle as the bigger gas lasers. They function as an optical oscillator by stimulating a chain reaction of photon emission inside a tiny chamber.

Generally, diode pumped solid state lasers (DPSSL) use photons emitted from semiconductor diode junctions to pump various laser media.

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 ...

CryoLaser was selected as a “hot topic” for CLEO 2013's central press event. Ultra-high power laser systems require diode lasers that are not just extremely capable, but also manufacturable at low ...

Researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses.

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.

Powerful laser diodes don’t come cheap, after all. However, as the technology trickles down to lower-end models, it’s likely that we could see economies of scale change that for the better.

The output of a single laser diode has been held below 10 W or so by adverse thermal effects and materials limitations. Now Alfalight is commencing a multi-million dollar project to develop a 50 W ...

Nagoya University researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA ...
