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 ...
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 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 ...
The interaction between the two light sources created a shadow on a screen that was visible as a dark area where the green laser blocked the blue light.
