    Powerful burning Laser

    DO NOT DO HOME TATTOO REMOVAL. Tattoo removal lasers are MUCH more powerful (like 5-10 watts) than diode lasers like the one in this instructable. The lasers used in tattoo removal are Argon gas lasers, in the IR spectrum, and they are pulsed by a special pwm circuit, and applied to the skin for 5-10 MILLISECOND bursts (depending on skin thickness/color). If applied in a constant on state, it would cut your arm off.
