Product Details

This handheld laser pointer uses the best materials, dual-diode design, standard 520nm wavelength, and multiple internal protections. The green laser beam is powerful, stable, and long-range. The maximum output is up to 4000mW (3000mW is also optional), the highest power we can achieve for a green laser pointer. To ensure stability and safety, we conducted repeated tests. All accessories are available, without any customs issues. We can develop lasers according to customer requirements. If you have any questions, please contact us via email.

Why is there a 4W green laser pointer?
For a green laser pointer, it is impossible to achieve 3W power with only a single laser diode. We use a dual-diode setup and an overdriving design, making 4W (4000mW) achievable. This model is the strongest green laser pointer. It has an efficient heat dissipation system, so you don't need to worry about the diode's useful life.

This output is really the most powerful in the world for the 520 nm wavelength.
The battery life is also excellent (32650 battery).

I purchased this product and a power meter. According to my repeated tests, its output power is 3800-3900mW (less than 4000mW).

I bought it because of the high power of 4000mW. However, after testing it with professional instruments, I found that the maximum power is only about 3800mW.

I couldn't wait to test this laser pointer as soon as I received it, and the output power was as high as 4W!

Added by N. X. Q. on February 09, 2026
I bought it mainly for scientific experiments, and I am very satisfied with its performance. The output power is stable at around 4000mW, which is essential for experiments.

This product uses a dual diode design, and according to my test, the actual power is up to 3800mW. However, it is relatively heavy, so it will be tiring to hold for a long time.

This green laser is really powerful! When tested outdoors, the laser beam can reach far away, and the visual effect is amazing.
