I am getting closer. How to see infared lasers invisible to the human eye! (REALLY WORKS!) - YouTube

How about this, is there an invisible laser that reacts visibly to an infrared or ultraviolet light? Or is that the same question?

Well, that puts a damper in my plan. I guess I will have to go with plan B. Using two different colors that combine to form a third.

Hi all. I am a fiber optics technician for the telephone company. I came to the forum to see if anyone can advise me on a personal project. And the question is........ Are there any two invisible lasers that, when combined (crossed,) produce a visible light?
