Have you heard about thus faster laser?

Should read this.
Wow.
The faster pulses achieved with the new technique result in a frequency comb with more widely spaced teeth. That property could be useful for calibrating telescope instruments called spectrographs, which slice up light from stars into various colors, aiding scientists in observations such as the hunt for planets beyond the solar system. Those spectrographs can’t distinguish frequencies that are too close together, so the instruments require a wide comb.

Faster pulses could also speed up certain kinds of imaging of biological tissues. And the laser could be useful for telecommunications, says physicist and electrical engineer Andrew Weiner of Purdue University in West Lafayette, Ind., who called the work a “tour de force.” Each color of light could carry its own stream of information in a fiber-optic cable.

The researchers “have achieved this amazing level of performance,” says physicist Victor Torres-Company of Chalmers University of Technology in Gothenburg, Sweden. “It’s up to us to think and dream what we could do with this light source.”

No, and it's a 100 times faster than what we currently have. That's pretty incredible.
Considering all the things they've been doing with lasers lately, like on the molecular and atomic scale, (they use lasers to manipulate small particles etc) I'm sure they'll be really useful in research.
