The question is not complete. There is no information about the procedure. No, the power is not the same if the procedure is medical. Yes, if the procedure is military and the laser is combat. I don't know where you can get it.
This information is absolutely fiction. Even when exposed to the deep layers of the skin, the laser beam penetrates into it only a couple of millimeters and then scatters, without causing any harm to the internal organs. The body of any person is actually equipped with a wonderful defense mechanism, which is, among other things, the skin itself, so getting to the vital organs is not as easy as it seems. Moreover, it is beyond the power of a laser beam, which was invented to help in solving problems with dermis, but not to harm. Let us examine, for example, the procedure for laser hair removal. The maximum depth of the hair follicle is 2.5-4 mm. The laser beam affects only the pigment (melanin) contained in the hair through selective photosynthesis. Melanin absorbs laser light and can heat up. That is, the only side reaction to the procedure may be overheating of the skin, which is expressed in slight redness, usually disappearing in a couple of hours.
