they use ruby's
There is nothing used in LASERs to stop the light from diffusing . . . LASER light is non-diffusing (coherent) simply from the way its light is made to begin with. Imagine yourself in a bathtub full of water, and you are sloshing water in all directions. This would be like incoherent, or diffuse light. Now imagine that you are in a bathtub and you use your hands to push the water from one end of the tub to the other . . . back and forth, back and forth. The water would be moving all in one direction. Let's also say that you put a little more energy in your pushing. At some point the water shoots out over the end of the bathtub in one direction. That is also how LASER light is coherent, travelling in one direction, and non-diffusing. About the only difference is that LASERs use photons, not water.
hand lasers i think
You get a special item from recusing a spy. He says it will help you aslong with the mission and he is correct. Just Jump or walk through the lasers when it's clear to go. That's the way to get through the lasers! :) Tell other people who have asked this question. It will help all the askers out there!!
It's kind of a joke item, but it can show where lasers are if you don't have the goggles. And he thinks of them as 'a lucky charm'. They're useless besides for finding lasers.
Many surfaces can be engraved by lasers, such as wood, plastic, metal, glass and stone. However, the results vary on each item and some products such as softwood can be engraved by lasers but in a bad quality.
