Not exactly sure what you're asking here since you've wrote 4 words. The title of the thread says "how much is a high power laser", so I'll try to answer you as best as I can. In terms of power, a high-power laser is hard to classify. Anything over 5mW can give you eye damage however I wouldn't call a 10mW laser "high-power". Probably 50mW+ would be classified as high-power.
Hope I could answer your very un-descriptive question.
i m terribly sorry, acctually i would like to try to delete a post for some reason, but i failed, and accidently post this, though great appriciate for ur concerns.
