Researchers at Nichia Corporation have demonstrated green InGaN-based lasers grown on c-plane sapphire, with lifetimes capable of supporting commercial applications. The demonstration of green ...

When the green laser beam passed through the ruby crystal, it created a region where the blue light was absorbed more intensely, forming a dark outline. This shadow effect shares similarities with ...

the laser is always on and turns off to form the pulses (the bits are non-light rather than light). The advantage of dark lasers is that their non-light pulses are more stable and become less ...

The green laser acts like an ordinary object while the blue laser acts like illumination. The interaction between the two light sources created a shadow on a screen that was visible as a dark area ...

Pigment-specific laser technology generates green, red, or near-infrared light to selectively target intracellular melanosomes or tattoo pigment. Pigment-specific lasers are also used to eradicate ...

As the aircraft scanned the water, it shone down a visible green light—a move to help first responders identify and remove remaining debris. The aircraft used by NOAA to conduct LiDAR scanning of the ...

A motorist was left momentarily blinded after another driver allegedly aimed a green laser pointer at his vehicle twice while driving along Keppel Road on the morning of Feb 7. Read more at ...
