What is a Laser?
Before we actually start to compare red versus green laser pointers, we need to have an understanding of what laser technology is.
Technically, “LASER” is an acronym for Light Amplification by Stimulated Emission of Radiation. In short, a laser is simply a concentrated light beam that is amplified to great brightness.
If you paid attention in class, you'd know that light is just electromagnetic photons that are energized at specific wavelengths. By optically amplifying a specific wavelength of light, we are able to achieve this concentrated beam of light.
Human eyes can detect a narrow spectrum of light. This is commonly known as a “visible light spectrum.” By varying the frequency range of this light spectrum, we can produce what we now know as red or green lasers.
What Is The Difference Between A Red And Green Laser?
The main difference between a red and green laser is the wavelength difference. A red laser has a longer wavelength of about 650 nanometers, whereas a green laser has a shorter wavelength of about 532 nanometers.
The mechanism used to produce these two types of lasers is also different. Red lasers generally use a diode and optics and are easy to manufacture. This explains why red lasers are so cheap to make.
A green laser pointer requires a special diode, a frequency doubling crystal, and a second infra-red laser crystal. Assembling them requires much more effort compared to red lasers.
Why do we continue to see so many red lasers being used in the home, commercial and industrial products? Basically red lasers were the first kind of lasers to be manufactured and started the whole “laser pointer” scene. Green lasers came about later and as you know by now, actually cost more to manufacture. However, green lasers have caught up due to improvements in technology and are starting to cost less.
Now that you have a basic understand of what a red and green laser is, let’s see why green lasers are better.
Green Lasers Are More Visible
A green laser appears brighter than a red laser because it is closer to the center of the visible spectrum. The photoreceptors in our eyes are more sensitive to wavelengths of light in the 520 to 570-nanometer spectrum. And guess which laser resides in that spectrum? That’s right...because green lasers have a wavelength of 532 nanometers, they appear brighter to our eyes.
In fact, a green laser can appear as much as five times brighter than a red laser. This makes green lasers a much better choice over red lasers. They are much brighter and can be seen even for thousands of feet away under optimal conditions.
What does this mean? For classroom or office pointing duties, green lasers can be easily seen even under the brightest of lights. For someone looking for an optical accessory for his or her hunting rifle, a green laser offers much better visibility over long distances.
In this review, we will look at how green lasers can be applied to two different scenarios: office laser pointers and laser sighting devices for rifles.
5 Best Office Laser Pointers
Lasers can be used for a variety of purposes, and one of them includes pointing out objects during presentations. The ubiquitous red laser pointer is a common office tool. However, since green lasers are brighter and easier to spot (and clearly you want the brightest laser pointer), we highly recommend green laser pointers. Why? Red lasers—at least the common commercial ones—can be almost impossible to spot in daylight conditions, especially in offices that are brightly lit. A green laser is more visible and can point out objects on a slide or whiteboard more effectively.
The Kensington Expert Wireless Presenter uses a green laser pointer that is ten times brighter than a typical red laser beam. It comes with two modes: engaging a flip instantly switches from cursor control mode to presenter mode.
The Kensington Expert Wireless Presenter has a long wireless range of up to 150 feet. Its wireless 2.4GHz USB receiver can be neatly stored inside for convenient and easy transportation as well. This device is uniquely paired so you never have to worry about wireless interference.
It’s fully compatible with Windows 7, 8, 10 and Mac OS X. So if you’re looking to control PowerPoint or Keynote presentations, this is the best laser pointer to get.
The Logitech Professional Presenter R800 has a brilliant and powerful green laser beam that is easy to see in brightly lit offices and works well on projection screens and flat panel displays.

5 Best Green Laser Pointers for Hunting
Red laser spotting devices have been around for almost twenty years. They were cheap to manufacture and worked well. However, green laser pointers started appearing on the scene ten years ago and have been widely employed by the police and military. The superiority of a green laser lies in the fact that the green laser dot can be seen almost twice as far as a red laser dot. The green laser also creates a prominent laser path for the shooter. For the hunter, the improved visibility and longer range is a significant benefit.
A green laser beam is also easier to see during daytime. Our eyes are trained naturally to see green colors better than red. This allows the hunter to acquire his target quicker under any light conditions.
The Crimson Trace CMR–206 is a universal green laser pointer that is designed to fit rail-equipped rifles and basically any firearm with a modern accessory rail. It offers the brightest green laser allowed by law.
The Crimson Trace CMR–206’s green laser can run on a single 1/3N lithium battery for two hours and also features an auto shut-off mode for power saving.
There are three modes of operation: momentary, strobe and constant-on. So whatever your preference is, you’re sure to find a feature that fits your needs. The CMR–206 is easy to install and can be quickly transferred from your current rifle to another firearm.
The Ade Advanced Optics was made for any standard rifle with Weaver or Picatinny rails. It can be easily attached and detached without fuss.
Made from solid steel and lightweight aircraft-grade aluminum, the Ade Advanced Optics is extremely sturdy. The green laser has adjustable windage and elevation and can be run on a single CR123 battery.
The Truglo Micro-Tac is a next generation weapon-mounted green laser pointer that can fit any rifle with a Weaver or Picatinny style rail. It is ultra compact, super lightweight and features a unique ambidextrous push-button for both right and left-hand operation.
The high-efficiency superconductor laser diode comes with pulse and constant-on laser modes. The Truglo Micro-Tac’s recessed off/on button also reduces accidental activation of the laser beam and automatically shuts off after 5 minutes of use.
The Vokul is an affordable green dot laser sight with an advanced bright laser optic. It emits an intense and highly visible green laser beam for both short and long range targeting.
Made from high-quality aluminum alloy, the Vokul is solid and reliable. Its windage and elevation are easily adjustable and customizable for day or night shoots.
The Vokul Tactical Green Dot Laser Sight comes with a 22mm metal Picatinny rail mount, a 1” rifle barrel clamp mount, an 8”-type mount, a pressure pad switch, one allen wrench and a 3V CR123A lithium battery.
The Barska GLX is a 3rd generation design standard green laser pointer for easy zeroing. The intense green laser beam is highly visible to the human eye, making this a perfect companion for hunters.
It comes with an external scope for easy elevation and windage adjustments for precise targeting. The Barska GLX is powered by a single CR–123A lithium battery which comes included with the kit.
Its diamond-cut tactical design comes with a unique feature – a crenulated-bezel edge for added protection. In times of emergencies, the Barska can be quickly detached for high-impact usage. The raised edges also protect the laser optics in such a scenario.
Red lasers have always been considered as a cheaper alternative to green lasers. But as you can see from our review, green laser pointing devices are not that expensive. Prices have gone down due to technological advances.
If you need a laser pointer for the office or classroom, then it makes sense to go with green. They are easily visible even under the brightest of fluorescent lighting.
For someone looking for a laser sight for his hunting rifle, you can’t go wrong with green either. It provides excellent visibility even in outdoors and under low-light situations.
The bottom line is this: our eyes naturally detect green colors easier, hence it makes perfect sense to pick a green laser pointer over red. We hope this information about the best laser pointers on Amazon has been helpful to you.
