Reflect laser lights or turn them off?

Question

This is for research for my novel. I've asked some laser lights questions awhile back on how they worked and if they give shock. How do you reflect laser light or turn them off at a cave, which is boobytrapped by them, when there's no deactivation/activation device in sight? Spray from aerosol can? Rocks thrown at center of laser lights? Reflection from mirror, without breaking the lights, not starting fire or causing a cave-in? Are they other ways? I'm interested to know. I believe there's a similar question asked before.

You' need to go to a site about defeating security systems. Defeating security systems may be illegal and dangerous.

Watch the first couple of episodes of MacGyver
