Since we started looking at these records worldwide, there have been at least 137,000 reported incidents of pilots seeing lasers or having lasers aimed in their face. This is happening *** lot because ...

It's not easy making green. For years, scientists have fabricated small, high-quality lasers that generate red and blue light. However, the method they typically employ—injecting electric current into ...

In a classic eureka moment, a team of physicists led by The City College of New York and including Herriot-Watt University and Corning Incorporated is showing how beams from ordinary laser pointers ...

Carolyn Trietsch recently defended her Ph.D. in entomology at Penn State. You can view her website or follow her on Twitter @carolyntrietsch. Laser pointers are perhaps the most abused visual aids in ...

Aim a handheld laser pointer at an aircraft in flight and you can blind or disorient its pilots and jeopardize the safety of the craft and everyone aboard. It’s a federal crime punishable by up to ...

Physicists have developed a method for drastically narrowing the emission spectrum of an ordinary diode laser, like that in a laser pointer, for use in compact chemical analyzers that can fit into a ...
