Optoma just put Hisense and Epson on high alert following the announcement of its Optoma UHZ68LV 4K laser projector, one that ...

Caltech researchers develop a platform to characterize ultrathin membranes for lightsails, advancing the quest for ...

Tractor beams using light or sound have existed for a while. Lasers can be used to create optical tweezers, a development that got Arthur Ashkin a Nobel prize in 2018 – so it is possible to move and ...

Achieving practical interstellar travel requires overcoming the immense challenge of reaching extraordinary velocities. To ...

Researchers have built a deep-ultraviolet microscope to study hard-to-analyze materials like diamond, offering a new way to probe their electronic and thermal properties at the nanoscale. This ...

Another benefit is the higher power output. Multimode laser diodes are able to generate higher optical power, making them ...

Scientists from China have developed high-performance colloidal quantum-dot (CQD)  surface-emitting laser array based on circular Bragg resonator (CBR). The CQD CBR laser array, leveraging ...

If shaving is growing tiresome, consider laser hair removal: This method damages hair follicles to reduce growth over time, ultimately giving more long-term results than using a razor. After ...

The electrons in the beam interact with the electrons bound to the metal atoms to create X-rays," he said. "At NIF, we use the high-power laser beam instead of an electron beam to make the X-rays ...

A new way to gauge distance using lasers can measure lengths of more than 100 kilometres to within a thousandth of the width of a human hair, and could be used to make better space telescopes.
