ingweza PWM is not just on and off but also there to regulate the intensity. If you are burning a picture with different levels of black. Then use pwm to darken the burn or create a light coloured burn. So yes it does in a sense at such a high speed you cant see the off, but it reduces the power and as a reuslt the laser is weaker. and of course the other way when the pulse is on for longer the laser seems brighter and therefor hotter. IT has 3 wires. The power + and - and the signal. When the duty is cycle is a )% then the laser will be off completely. hope that helps.
