NASA tested laser communications from space with a video of a cat chasing a laser dot! Psyche beamed the video about 19 ...

Bogey, a playful 9-month-old with a charming bend in his tail that makes him irresistible, is GV Wire's adoptable pet of the week.

Head-mounted lasers are easier to install and maintain, but their accuracy changes with movement of the machine’s Z-axis: as the head goes up and down, the red laser dot moves horizontally and ...

Flowing quantum dot solutions enhance heat dissipation, enabling stable high-speed pulsed operation and tunable color output for next-generation optical devices.

It is getting harder to find home laser printers, and earlier printer technologies such as dot matrix are almost gone from people’s homes even if you’ll still see a few printing multipart ...

Used to print multipart forms and address labels, the tractor and sprocket mechanism in these devices handles thicker media better than laser and inkjet printers. Also known as a "serial dot ...

Scientists from China have developed high-performance colloidal quantum-dot (CQD)  surface-emitting laser array based on ...

The quantum dot (QD) laser should, theoretically, solve this problem. In 1982, Japanese researchers first predicted, by theoretical modelling, that QDs — semiconductor nanosized crystals ...
