If I purchased a 40 watt fiber coupled laser with a collimated lens at the end of it could it be converted to 532nm green just by placing "crystals" in front of the collimated beam and adjusting the lens to get a different green focal point beam? Sounds simply but would it work? This would be a simple cheap high output green 532nm laser. Please respond if you can help or have a working knowledge of this type of arrangement that I want to try to accomplish!
