When you flip a switch or power up your smartphone, the last thing on your mind is whether that light could be messing with ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work with the highest possible focused laser peak power, which is the ratio of ...

Ultrashort laser pulses—that are shorter than a millionth of a millionth of a second—have transformed fundamental science, engineering and medicine. Despite this, their ultrashort duration has made ...

Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

When Wendell Lonergan landed a job at Nautel — formerly Nautical Electronic Laboratories — fresh out of college in 1978, he didn’t realize it would be the one and only job he would ever apply for. Now ...

Laser activation during endourological surgeries inevitably generates an excess of energy that is ultimately converted into thermal energy, resulting in an increase of the surrounding temperature. As ...

Shanghai scientists develop ultranarrow bandwidth mode-locked laser with a widely-tunable pulse duration. Shanghai’s ultranarrow bandwidth mode-locked laser. Click for info. Ultranarrow bandwidth mode ...

Abstract: This experiment aimed to improve the pulse shape and the pulse duration, with phase modulation of the seed laser pulse with spatial light modulator before amplifier stage and the employment ...

Researchers developed an ultranarrow bandwidth mode-locked laser with a widely tunable pulse duration, enabling controlled output, for various applications Lasers have widespread applications as a ...
