Class I lasers are not harmful to the eye. Class II lasers are only harmful if the blink reflex is defeated. It doesn't make any difference what the visible color is. UV lasers can be dangerous at very low power output.
If your kid chases the light and runs into walls or falls off of long drops, you should avoid that.

What color laser beam does a DVD drive use?
a red laser like a CD
What is the typical power of a green laser pointer in milliwatts?
A standard green laser pointer has a power of between 4 and 20 milliwatts. A red laser, for comparison, has a power of less than 5 milliwatts. The beam of a green laser can often be seen, while the beam of a red laser cannot be seen.
What are the uses for a CW laser?
A continuous-wave laser, or CW laser, is part of many items. A laser pointer's red beam is an example of a CW laser. CW lasers are also used in holography.
In a vacuum space the red laser beam travels faster then the beam of microwaves true or false?
Both beams travel at the same speed.
If you wish to spear a blue fish with a red laser beam you should compensate for refraction between the air and water by aiming your laser?
directly below it
How do you detect a laser beam?
You can see light rays with dust, flour, etc. If you turn on a flashlight, you can drop dust right where the light travels to actually see that beam of light. The same thing happens with red laser beams.
What color is the laser beam in a DVD drive?
Red - its 650 nanometer wavelength puts it squarely in the middle of the visible light's red spectrum.
What was the cyclops power?
Cyclops could shoot a red laser beam out of his eyes. He also dated Jean Grey.
What color laser is used in a DVD drive?
its, mostly Infra Red, a colour you can't see.
What is the difference between a red dot sight and a laser sight?
The difference is that red-dot sights have contained aiming reticles, whereas laser sights use an emitted laser beam that must fall onto a target. Red-dot sights are used mainly for more accurate ADS (aiming down sight) firing and laser sights allow for less-accurate, but made more so, shoulder-firing.
Do burglar alarms have infra red lasers?
There are multiple types of alarm systems and sensors available for them. While low-powered lasers could be used, they are not usually. More common is what is called a PIR, or Passive Infra-Red detector. These detectors usually give a "cone" of infrared light which detects movement, whereas a laser beam would need to be "broken" (the beam would need to be interrupted). Because of the coherent nature of a laser beam (the beam travels in a narrow, straight path), compared to the wide coverage of a PIR motion sensor, lasers are rarely used.
What kind of radiation does red laser pointers emit?
Red laser light.
