America unveils most powerful laser pointer

But now let's use the same power laser, 5mW but green, as you said, it points to 2000 meters or more, and it's very interesting, the 5mW green pointer is a visible beam at night (like a lightsaber in star wars) but I don't bother with 5mW green I'm currently waiting for a green laser with a power of 30mW, so I'm worried because if I receive the laser indirectly (through the reflection of the beam) use it.

We can make 5 megawatt high power laser pointer stars on Earth. When my friends in Hollywood found out what they were showing on the big screen was outdated, I can already imagine their disappointment. We have the real thing here," added the former actor. NIF, located at Lawrence Livermore Laboratory, about an hour's drive from San Francisco, can focus 192 powerful laser beams on a single point, recreating stars or Temperature and pressure in the cores of giant planets.
