Anyone who knows lasers, think of power as a problem but there is a solution. Usually you would need like 4 car battaries to run one. A disposable camera is what you need it collect power from 4 AA batteries a large amount of power in one short burst of pure power which is the flash. Well if you attach it to a laser module you have a high powered laser.

The technology was never thought of before because the power would be too erratic but with a bit of transistors and other chips it will clear it up. I have tested this and made a prototype. In case you are wondering the laser module can be found in a CD/DVD drive but if you can find a blu-ray laser which is stronger.
