Hi all, my name is Kairos and I'm from Singapore. My first encounter with lasers come from laser pointers, those cheap ones which emits red light. I enjoy seeing laser shoot across long distance and appear on another far away place, haha. I hope to learn how to make lasers that are powerful enough to shoot to the moon. Hope you guys could teach me a thing on two on how to make a cheap but powerful laser. Nice to see all of you laser fans!
