A laser phased array directed energy system has been designed and simulated. Lubin and Hughes calculated the requirements and possibilities for DE-STAR systems of several sizes, ranging from a desktop ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

Researchers at the Lawrence Livermore National Laboratory have created the world’s highest peak-power laser diode array, capable of creating up to 3.2 megawatts. The new device will be used in ...

How do you send man-made probes to a nearby star? According to NASA-funded research at the University of California, Santa Barbara (UCSB), the answer is simple: assemble a laser array the size of ...

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 ...
