Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a factor of over ten thousand – ...

A team at Harvard and Vienna University of Technology have invented a new tunable laser that uses a series of rings to smoothly emit many light wavelengths from a single chip. The laser could replace ...

However, to burn through materials at safe distances requires tens to hundreds of kilowatts of power in the laser beam. The smallest prototype laser weapon draws 10 kilowatts of power, roughly ...
