Thanks for the info on the Photolysis HR. Other companies do indeed make flash lamp pulsed light systems. In fact Lumenis, maker of the Lightsheer laser makes an IPL (intense pulsed light system) called the VascuLight which they do not promote heavily. It is used to treat leg veins and for hair removal.
Ironically, I work with flashtubes in my job. One of the flash units I work with is 50 Joules. That’s just about right. Maybe I should do some experimenting. They can definitely burn too! I don’t know of anyone who has touched one while it was lit. Pulse width is about 1 ms for the 50 Joule version.
BTW the after photo of that bodybuilder’s chest that they said was taken one month later is what my chest looks like 1-2 days after a Lighsheer treatment. I’ll have a few red spots here and there (no ingrowns though) and totally hairless. Of course the day before the treatment I shave my chest totally clean with a Mach3 Turbo. Unlike other lasers, Lumenis recommends that the skin be clean shaven before a Lightsheer treatment. You are less likely to be burned if the hair is completely shaved off before treatment, leaving only the hair below the skin.
