Green Laser Vs Red Laser Power

Red at 633 nm vs.

Green laser vs red laser power.

The green light is generated through a multi step process usually beginning with a high power. While a green beam appears brighter to the human eye and often produces a crisper point or line it is also more expensive and consumes more battery power. Just looking at the red and green lasers side by side on the wall in my house the green laser did appear to be brighter. The human eye is more sensitive to the colour green compared to red but this not necessarily mean that a green laser will appear brighter for you.

Green laser pointers appeared on the market around 2000 and are the most common type of dpss lasers also called diode pumped solid state frequency doubled dpssfd they are more complex than standard red laser pointers because laser diodes are not commonly available in this wavelength range. So producing the same power output as a class 3r green beam. Outside of the obvious difference in color there are significant differences between red and green laser levels. Green can be used inside or out but green is much.

Green laser levels use high energy in order to generate the green beam. Red vs green vs blue vs yellow by wesley fenlon on aug. For this reason green lasers are more complicated slightly larger and more time consuming and thus expensive to build. Red lasers are suitable indoors around the clock or outside from dusk to dawn.

The downside is the power requirement. This will lead to less total operation time compared to a red laser level. Green at 532 nm the diagram below compares a 5 milliwatt red laser 633 nanometer wavelength with an equivalent 5 mw green laser 532 nm wavelength. Recently a green laser was introduced to the laser sight family.

These laser levels use more power. As you can see the red laser has a visual interference hazard distance that is about half of the green laser. Green lasers drain batteries quicker and at least for now they re also more expensive to manufacture. Knowing which to pick is dependent on how you intend to use your laser level as well as your budget.

So are they really worth the trade off. 30 2010 at 9 20 a m. Green lasers are more complex. When comparing red and green lasers of the same power which appears brighter is largely determined by the colour and texture of the.

Ask any worker and he d tell you that green laser levels are more expensive than their red counterparts. Green vs red beam laser level. Green laser level operates at a higher temperature this makes the green diodes more prone to damage. Know your laser spectrum.

Building a green laser requires a special 808 diode a second infrared laser crystal and a frequency doubling crystal and these parts must be carefully aligned to produce the green laser image. I wanted to put the theory to the test.
