Hair removal, but alternative interpretations may also be valid

laser hair removal involves blasting a small radius with intense light, which burns the hair follicles (the idea is that the dark follicles absorb more light and thus more heat, so you can burn the follicle without burning the skin around it; it works better for people with dark hair and light skin, of course).

I’m assuming a hair removal laser, but I may be incorrect. Perhaps this person is a fan of laser bowling. We may never know.
