A green laser will happily burn out sensors, but you'd have to really work at it to burn up all of the sensor because the laser light will typically only fry a couple of pixels at the time.

It's not a magical 'point and fry' solution, more like a take up position and stand around for half an hour or so while the laser systematically hits every bit of the sensor long enough to fry it. A hammer would be a lot more effective (assuming you can reach the camera).
