Super Powerful Blue Laser Pointer 5000mW 450nm with NUBM08 Diode

This laser pointer has high power, good stability, and low divergence. These features meet my usage requirements.

The test result is 4800mW+, which meets my expectations. However, the laser divergence angle is too large.
If you want to use it at a distance of more than 2 km, you must install a beam expander.

I tested this product with a laser power meter. The result is 4900mW+. For the 5W output, it's very affordable.
