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.
A straightforward room-pressure air or nitrogen laser design
that provides good performance without requiring expensive or
hard-to-obtain parts or materials, and which can be constructed
without access to a machine shop.
A somewhat more advanced room-pressure air or nitrogen laser
that is also relatively inexpensive and does not require
expensive or hard-to-obtain parts or materials, but is
significantly less easy to construct.
An unhappy discussion of the Scientific American “Amateur
Scientist” nitrogen laser or, to be more accurate, of
Jim Small’s explanation of it.
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
The list of Research Reports
for more information about lasers and other things I work on.
