Optical innovation could calm the jitters of high-power lasers

The Berkeley Lab Laser Accelerator (BELLA) Center at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has developed and tested an innovative optical system to precisely measure and control the position and pointing angle of high-power laser beams with unprecedented accuracy--without interrupting or disturbing the beams. The new system will help users throughout the sciences get the most out of high-power lasers.
