Short segment from a YouTube video by Jeff Langmaid arguing that visible-light lasers need ~10–12 milliwatts for effective penetration (noting a competitor uses 7.5 mW which is marginal) and that infrared lasers can use much higher power, with ~1000 milliwatts cited as ideal for maximum penetration.

Questions this video answers

Around 10 milliwatts; recommends between 10 and 12 milliwatts.

7.5 milliwatts (diode).

About 1000 milliwatts (maximum penetration).

The ideal amount of power for all visible light is around 10 milliwatts. If you can get there, that's fine. Now, most other companies will use. Our number one competitor uses a 7.5 milliwatt diode. That's okay. But if you get any lower than that, you're just not going to have any power, any, any penetration at all. So you do want to have. With the visible light, you want to have between 10 and 12 milliwatts. And for the infrared, you can go as high as you want. Most of the research shows that 1000 milliwatts, again, is the ideal amount of infrared, and that allows for maximum penetration.
