I've got the plans for a device to do the same with sound.

I'm waiting until BLu -ray players get sheap enough for my to scavenger parts for my pocket - LASER  (DEATH RAY)

you want the writing lasers, and not the reading lasers.
also, afaik Blu-ray isnt stronger than normal dvd-burners.  just get regular dvd burner lasers and hook em up to batteries. one is enough to light a cigarette i wonder what many would do when focussed in one point.
hmmm i only have acces to one dvd burner laser but ill be experimenting wit hit one of these days.
