Recent developments (early 2010) in LASER technology used in LASER home theatre projectors have made 445nm Direct Blue LASER diodes available in the commercial marketplace. This makes it possible to construct extremely high power portable devices at ridiculously low cost. With output power far greater than any other visible handheld LASER, the Arctic Blue LASER equipped with the 445nm Direct Blue LASER diode if mishandled, can lead to serious injuries and permanent vision impairment, as well as personal injury.
