If you are looking to buy a high-power laser or have a laser pointer already, you may wonder exactly how far any specific mW output power will go on a clear line of site. This is because when browsing for the best model, you’ll run into hundreds of different beam colors, power strengths, and design features. Having a little knowledge of what these numbers mean and how color affects the visible range of a laser is incredibly useful.

When searching for different handheld laser pointers online, you may notice various features depending on the models you browse. There are things like key lock switches, momentary vs. constant on/off buttons, laser heads and caps to attach, duty cycles, and more....

We've all seen different types of lasers in Hollywood TV and films. Whether attached to a weapon in an action movie, a threat from a supervillain in a comic book movie, or different science fiction scenario, there is a common theme. Lasers are a powerful technology...

In a perfect vacuum, like space, an unimpeded laser beam would theoretically travel indefinitely, only limited by the expansion of the universe and the quantum effects on a photon over immense timescales. Sure, your eyes would lose sight of it at some point about 20 miles out, but the light will continue to travel nonetheless. While on Earth, several factors come into play within our atmosphere, altering a beam’s path.

If you're looking to buy a laser pointer, you probably have some questions. There are a lot of different output powers, beam colors, design options, safety features, and prices to consider. Choosing a suitable laser can be daunting if you're unfamiliar with handheld...

So, how far can you see a laser beam? For typical laser pointers you find for sale online, the beam can be clearly visible for a few hundred meters under optimal conditions. High-powered lasers can reach further, with their beams visible for several kilometers, albeit with decreasing intensity. The perceived distance also heavily depends on the observer’s location relative to the beam’s path and the surrounding light conditions. In darker environments, the beam appears more distinct and can seem to travel farther.

The Earth’s atmosphere is a mixture of gases, particles, and varying temperatures and pressures, all of which interact with and affect the propagation of a laser beam. This interaction, known as atmospheric attenuation, can cause the laser light to scatter, absorb, and refract, diminishing its intensity and visibility over distance.

2022 is coming to an end, and what a year it was! Now is a great time to look back and reflect on all that this past year had to offer and remember what we are grateful for. This year was a big one for the entire BigLasers.com family, and we're proud to share that...

At its core, a laser emits light through a process called stimulated emission, resulting in a highly focused and coherent beam of light. LASER stands for “Light Amplification by Stimulated Emission of Radiation.” A laser beam is incredibly directional, unlike regular light sources, which scatter light in all directions. This characteristic allows the light to stay narrow and level (straight) over long distances. This is why a laser beam appears as a straight line in the night sky for applications like star gazing and astronomy.

The journey of a laser pointer beam is a testament to the intricate interplay between light and our atmosphere. We’ve covered output power versus color and expected range for a variety of handheld options. But that doesn’t mean you may know precisely what you need for your specific laser use. But if you know where to look, you can get expert laser advice and assistance to ensure you’re going with the most suitable laser for whatever you need.

But you shouldn’t be considering visibility alone. Addressing the safety implications is crucial to ensure a laser operator’s and spectators’ safety. Powerful lasers can be dangerous, potentially causing eye damage and disorientation, even being able to start a fire with burning lasers 500mW+. There are common sense operation factors to keep in mind to keep your laser use safe:

After all, if you need your laser to be visible at 100 yards in the flush sun, you cannot go with the lowest power out there. Read this article, and you’ll have a much clearer understanding of how milliwatt (mW) Power, color, and beam width impact your laser output.
