The DRDO-developed system is equipped with a 2-kilowatt laser beam that can destroy enemy drones at an effective range of 800 to 1,000 metres. It is already in active use by the Indian Army and other ...

As demand for next-generation semiconductor chips grows, a team of researchers has succeeded in laser-drilling the world's tiniest circuit board holes, measuring a near-inconceivable 3 micrometers ...

Abstract: Optical frequency chirp of an external-cavity laser is linearized by optimizing the modulation waveform for long-range FMCW optical ranging system. The modulation signal of the laser is ...

Abstract: This research pioneers the application of a femtosecond laser Burst-Mode technique for the fabrication of waveguide Bragg gratings (WBGs) within planar lightwave circuits (PLCs).

Needless to say, we’re fascinated by LEDs, laser diodes, and other blinkies. Although we can get just about any light emitting thing, the data sheets aren’t always accurate or available.

The trick is to add an array of photovoltaic cells specifically tuned to an IR laser’s wavelength. A ground system then directs a high-intensity laser beam onto the aircraft’s cell array to ...
