Scientists have shown off a new laser that boasts an incomparable mix of speed, short pulses and power. That's newsworthy in and of itself, but this laser, developed by researchers at the University of Konstanz in Germany and, here in the U.S., at the National Institute of Standards and Technology, could also lead to a 100-fold increase in the sensitivity of observatories searching for extrasolar planets. The laser itself is the size of a dime, and pops out 10 billion pulses per second with an average power of 650 milliwatts.
