The Difference between Green and Red Laser Pointers

Laser pointers have many innovations and the first two of these technologies’ roots are the red and green laser pointer. The Red laser pointer is the grandfather of all those latest amazing discoveries like the blue laser pointer, violet and pink. Green laser pointer on the other hand is the second discover next to red lasers. If you’re new to the world of laser beam technology you would surely be wondering which amongst these two is better, more powerful, cheaper, brighter and cooler to use. Here are some categories that classify the difference between these two laser pointers:

• WAVELENGTH

Red Laser Pointer is the simplest type of laser color that we have today – it is red because it emits light with a wavelength in the red spectrum that could have different color intensity between 620nm –750nm while Green Laser Pointer on the other hand emits light within the green spectrum which can also vary in its color intensity between 495nm to 570 nm depending on its use.

• VISIBILITY

The human eye is most sensitive to a light emitted at a wavelength of about 555nm for which green spectrum belongs. So obviously, green lasers are more visible than red laser pointers at about 50 times making it more suitable for star gazing and presentations. Green laser beam is highly visible both at night and day time.

• POWER

Another difference is their cutting edge capabilities. Amongst all pointers produced, red laser pointer leads this category. At present, the most powerful laser pointer ever developed is the Red Nitro Pro pointer with 2 watts of power manufactured and produced by Vectralasers which is truly a leader. If you see videos that show how 125mW green laser pointer light 3 matches or a 200mW green portable laser cutting a trash bag, well, can you imagine what a 2000mW red laser pointer can do?

• Structure

Another difference between these two is the engineering involved in constructing these two wonders. The green laser pointer is more complex than the red ones considering the fact that there are no green laser diodes that can be used to produce green light outcome, so, rather than spending more research, an 808nm diode is used while utilizing special crystals to achieve green spectrum.

In with these, we now know that they are different in many ways be it in color, price and the ability to burn.
