In a more everyday context of laser application, it's important to realize that everyone has come across barcode scanners in stores, or has seen laser shows in nightclubs, or used a laser scanner or even a laser printer. And of course, how could anyone forget the legendary laser sword fight between Luke Skywalker and Darth Vader in “Star Wars”?
This year, commemorating the invention of the laser, LaserFest is presenting various events and display shows in locations all over the world. LaserFest is a year-long collaboration between the American Physical Society, the Optical Society, SPIE, and IEEE Photonics Society.
On May 16th, there will be a laser show in England, an exhibition in Germany, a symposium in Canada, and a conference in California.
