Tekhnoscan presents a new powerful tunable source of UV to blue-green ultra-narrow-linewidth radiation on the basis of tandem including a Ti:Sapphire laser and efficient resonant frequency doubler.

One of the more exotic technologies being explored for Army networking is ultraviolet communications. It can be employed for non-line-of-sight (LOS) communications or direct LOS, and it is harder for ...

BOULDER, Colo. – Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength.

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...
