The laserfocusworld.com Lasers & Sources channel features articles and other content that discuss the design and applications of all types of lasers, amplifiers, and other advanced sources like LEDs.
Serendipity in the form of an active photoconductive material—a semiconductor phase embedded within glass—that generates a current reliably for months when exposed ultraviolet...
A breathing soliton laser helps researchers discover modulated subharmonics, a new state of nonlinear systems, which contains both synchronized and desynchronized signals.
Researchers in Spain create nontoxic colloidal quantum dots that preserve the advantageous properties of their heavy-metal counterparts—and use them in high-performance SWIR photodetect...
Compared to electrical detection, an all-optical ultrafast laser technique provides the resolution needed to explore electron transport within ballistic and coherent regimes.
A team of researchers immediately knew something was different about their wakefield laser accelerator when they started shooting at the Texas Petawatt Laser: adding aluminum ...
