- Congratulations! This is extraordinary. Thank you very much for sharing.
- Hooray, at last you have done it! I knew that this type of setup would work and that our german engineers are on the wrong way with their Pr+++upconversion- fiber-laser. Now it is possible to build a He-Ne-replacement laser with proper beam quality. I would like to know a little more about your laser, e.g. the conversion efficiency. The Pr-Ion is the most promising laser medium I know. Great work, go on !
