The green laser acts like an ordinary object while the blue laser acts like illumination. The interaction between the two ...

When the green laser interacted with the ruby, it altered the crystal’s optical properties, increasing its absorption of the blue light and casting a visible shadow in the shape of the green laser.

A semiconductor laser that emits light in the 400-450 nm range. Although it was very difficult developing blue lasers, which emit smaller wavelengths than other colors, blue lasers became ...

The ability of new blue-light semiconductor lasers to better perform precision cutting, patterning or welding of copper will make electrical and electronic component manufacturing cheaper and more ...

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

Researchers at Toyohashi University of Technology, in collaboration with the Indian Institute of Technology Madras and the National Institute of Technology, Gifu College, have developed a novel system ...

co-recipient of the 2014 Nobel Prize in Physics for the invention of blue light-emitting diodes, founded Blue Laser Fusion in Palo Alto, California, in November. Partners include Hiroaki Ohta ...

However, such systems cannot match the small size and low-cost benefits provided by semiconductor laser diodes that directly emit green light. The first attempts to fabricate blue and green diode ...
