    Need help to build a laser

    Hello. Today I've found an old Playstation 1 and noticed it has a blue diode. I wonder if I can turn this diode into a burning laser ? The input for the PS1 is 7.5V, would a 9V battery work ? And if its possible, how do I do that ? I've heard that I need to buy a driver or something. Thanks :)
