Lasers at the Joss Research Institute
- A straightforward low-pressure nitrogen laser design intended for DIY folks
I am also working on some more advanced designs; you may want to take a look at the low-pressure nitrogen laser pageset that is among my research reports, though you will want to be aware that I include lots of information about failures as well as successes, so you are probably in for a bit of a slog.
- An unhappy discussion of the Scientific American “Amateur Scientist” nitrogen laser or, to be more accurate, of Jim Small’s explanation of how it works.
- Rebuilding a damaged Avco-Everett C5000 nitrogen laser head that we acquired surplus on eBay
- Testing and using a surplus Molectron [low-pressure] nitrogen laser, also acquired on eBay (includes some information about tuning organic dyes that you are pumping with the nitrogen laser)
- Repairing, checking, and using a PRA LN-1000 [TEA] nitrogen laser, also acquired on eBay, with a note about tuning organic dyes under TEA-N2 pumping
- A bit more information about nitrogen-pumping organic dye lasers
- A “photographic tuning curve” for 4-Methyl-Umbelliferone, pumped by a low-pressure nitrogen laser
- A photographic tuning curve for 7-Diethylamino-4-Methyl-Coumarin, under flashlamp pumping
- A flashlamp-pumped organic dye laser that I built primarily from parts we acquired on eBay, with a photographic tuning curve for Rhodamine 6G
