Scientists have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. They also have shown that this type of laser, when used as a frequency comb -- an ultraprecise technique for measuring different colors of light -- could boost the sensitivity of astronomical tools searching for other Earthlike planets as much as 100 fold.
