Utility-scale concentrating solar power (CSP) systems that produce electricity using lenses or mirrors to focus radiation on thermal collectors or photovoltaic cells draw criticism from environmental groups for taking up too much desert land, thus displacing certain animal and reptile species.

"Using ultra-short light pulses gives us the ability to focus in a well confined region and the ability for intense radiation, " said Parigger.

ENGADGET: Researchers develop femtosecond laser that can diagnose, blast cancerous tumors

And that depends on being able to see the lower-energy radiation, in order to pinpoint what it was that exploded (gamma rays are impossible to focus, so the location of a burst is known only approximately).
