Many people equate lasers with a sci-fi battle in a galaxy far, far away or, closer to home, with grocery store scanners and compact disc players. However, an ultra-fast, ultra-intense laser, or UUL, with laser pulse durations of one quadrillionth of a second, otherwise known as one femtosecond, could change cancer treatments, dentistry procedures, precision metal cutting, and joint implant surgeries.

Laser treatment transforms MDF producing startling image of rare wood grains
