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 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.
