Blue
I think the color of the laser is blue
Blue thus the name.
*BLU* ray the answer just in case you missed it is blue
what is the colour of blue ray disk
Blue, which is why it is called a Blu-ray.
The military satellites use a blue/green or aquamarine color LASER beam to communicate with submerged submarines.
Well, darling, the color of the laser used in a DVD drive is typically red. It's not like a rainbow of colors shooting out of there, just good ol' reliable red getting the job done. So, there you have it, red is the answer you were looking for.
I would expect red unless it is a blu-ray (that is blue)
A laser light appears as a bright, focused beam of light that is usually a single color such as red, green, or blue. It is coherent and does not spread out like the light from a flashlight, creating a sharp and visible line across surfaces.
red n with blue ray disk blue
There's not really any such thing. One common and therefore cheap type of laser diode emits a red light, as does the fairly common (or at least it used to be common; the diodes are so much cheaper I imagine they mostly use them now) laboratory helium-neon laser. So if I had to pick a single color that was "common" I'd say red. There are green and even blue laser diodes now, but they're more expensive than the red ones and therefore aren't as ubiquitous.
