Laser source

Silicon cascade

Nature Photonics volume 2, pages 132–133 (2008)Cite this article

After almost 50 years of laser research, efficient and compact laser sources operating in the mid-infrared region from 2 μm to 5 μm are still lacking. Now, cascaded silicon Raman lasers look set to provide a convenient answer.

Although lasers presently cover a far broader wavelength range than could have been envisioned when they were first invented in 1960, the application-rich mid-infrared region between 2 μm and 5 μm remains a virtually untouched and unexploited territory.
