I would expect red unless it is a blu-ray (that is blue)
red
A CD drive uses an infrared laser to read the data. An ultraviolet ray is used in Blu-Ray players, which gives them a much higher storage capacity.
Laser light comes in various colors depending on the type of laser being used. Common colors include red, green, blue, and violet. The color is determined by the specific wavelength of light being emitted by the laser.
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.
infrared color
The color of a laser beam is determined by the type of material used in the laser, such as a specific gas or semiconductor. These materials emit light at a specific wavelength, resulting in a single-color beam. Additional optics can be used to combine different lasers to produce multiple colors in laser light shows.
The old laser printers used He-Ne laser , and the modern laser printers use infrared laser .
A monochrome laser printer is used for printing in one color: black.
Laser paper is used by laser printers to produce black & white and color images. Laser printing is a cost-efficient alternative to inkjet printing, and is most popular in business environments where a larger amount of printing is done.
I believe it is the argon laser.
A laser is used to alter the internal metal alloy layer of the CD-RW. The strength of the laser can be varied and this allows the alloy to be manipulated and the data on the CD to be changed.
A laser generates an electromagnetic wave operating at light frequencies.
