In this episode of Photonics Hot List:
U.K.’s Defence Science and Technology Laboratory and Ministry of Defence aim to bring warfare further into the modern realm, after successfully demonstrating the effectiveness of an armored vehicle-mounted high-power laser energy weapon.
The shortcomings of conventional image sensor-based machine vision systems hinder their performance in challenging lighting conditions. But in work detailed in Nature Electronics, researchers from Hong Kong Polytechnic University have developed a photodiode-based solution.
A team of Stanford University researchers and engineers have brought the powerhouse that is a Ti:sapphire laser from bulky and complex to tiny and inexpensive. In a process involving a waveguide and a ring resonator, the new chipscale Ti:sapphire laser is already breaking ground.
