Mechanical shutter shapes laser beam.(IN THE NEWS: Scanning for ideas)

To get the most out of a laser, whether for communications or measurements, it must often be shaped or sliced into small sections. One reliable and inexpensive method of doing this is to use a electromechanical shutter, such as those designed and built by nmLaser Products, Sunnyvale, Calif. (nmlaser.com). They rely on an optically coated flexure beam to cover the window and prevent the laser beam from shining through. Energizing the toroidal electromagnet, however, makes it pull the cantilevered beam down, letting 100% of the laser beam pass through. If there is a power failure, ...
