As some of you may know, I am a high school student. Next year I am planning on entering the Intel Science Fair. I was thinking of making a LED pumped Dye laser. My problem is not the construction, I have a full CNC shop at my disposal and basically unlimited funds, I am wondering if I can actually get to the threshold needed. While I cannot tell you exactly what LEDs I will be using, I can tell you that it will be about 220W of optical light at the required pump wavelength. That is not the input power, but rather the optical power out of the LEDs. I was planning on having a flowing system for the dye in addition to water cooling the dye and LEDs.
What's your input on this? Can it get to the threshold for lasing with that?
