This laser can use to kill cockroaches?

Even small amounts of laser power, such as just a few milliwatts, can cause permanent eye damage. Higher power levels, exceeding 500 milliwatts, can lead to skin burns. The risk of harm is influenced by several factors, including the laser's power output, wavelength, beam size, and duration of exposure.
 

I hope the guy was wearing safety glasses because : :biggrin:
