Multi-wavelength light sources are required for optical transceivers to increase data. However, scaling the laser array size increases thermal crosstalk, which may affect laser efficiency and ...

The videos from [styropyro] are always amusing and informative. However, ironically for him, he is alarmed that many green laser pointers are more powerful than they are supposed to be. Sure, you ...

Principles of supersymmetry have been used to boost the performance of an array of solid-state lasers. The work was led by Mercedeh Khajavikhan at the University of Central Florida in the US. Her team ...

The development of monolithic arrays of high-power, single-mode semiconductor lasers is set to bring big benefits to the printing, coding and marking industries. Printing is arguably one of the most ...

Lawrence Livermore National Laboratory (LLNL) has installed and commissioned the highest peak power laser diode arrays in the world, representing total peak power of 3.2 megawatts (MW). The diode ...

Lasers—yes, lasers—could propel a space probe that would sail at 25% of the speed of light, making other stars reachable within human lifetimes. Receive emails about upcoming NOVA programs and related ...

This site has looked at arrays of laser modules for launching into space several times before and considers it a very promising approach. Jordin Kare had a proposed development plan to demonstrate a ...

Scientists in Belgium are claiming a breakthrough advance for integrated photonics by fabricating an array of laser diodes on a large silicon wafer typical of those used in volume semiconductor ...

Tunable laser arrays constitute a cornerstone of modern high-capacity optical networks, providing flexible wavelength sources for wavelength-division multiplexing (WDM) and advanced modulation schemes ...

A powerful 70 gigawatt laser propulsion system that could accelerate an 100 kilogram object over 122 seconds to 2% of light speed (6000 kilometers per second) would also be able to fire kinetic ...

Ring microlasers are eyed as potential light sources for photonic applications, but they first must be made more powerful. Combining multiple microlasers into an array solves only half of the problem, ...
