If hydrogen adsorbed on suitable catalysts can be made to desorb for
example with UV light, and if then a transition of the H atoms to a
compressed state in desorption also in turn causes the emission of UV
light (without focus on any theory in particular, although R. Mills has
studied such emissions with his Hydrinos) in a positive feedback loop,
one such laser might be possible, but it all depends on how probable
such transitions are. They are likely to be very rare with ordinary,
untreated hydrogen-active metals (Ni, Pd, Pt, etc) or also more complex
catalysts as used in commercial chemical reactors, causing them to go
unnoticed most of the time. So, it's unknown whether such laser would be
actually feasible in practice.
Although it will not work for a laser, with these mechanisms in mind,
perhaps a reactor composed of a very long coiled tube with the active
material coated on its internal walls could work more efficiently than a
big chamber with loose powder, while still being in principle overall
relatively simple to craft. The tube could be coiled around a heater of
some sort, and tube geometry and gas admission would have to be such as
to maximize repeated hydrogen contact with the catalyst coated on the
internal walls (e.g. a straight tube might not work well and a
free-flowing system could be better than one where hydrogen only very
slowly diffuses through the material) instead of just absorption into
the lattice as done in many gas-loaded LENR experiments.
I'm aware that one experiment by Mills or somebody else to verify his
theories used a long nickel tube in an electrolytic cell, but that would
be different than what I am thinking about here.

Hi Bill,
Your thought about "critical volume" is intriguing and brings up the
possibility of efficient self-lasing due to adsorption/desorption and
catalysis. Of interest would be the violet H line at 410 nm for which
there is already a secret US Navy weapon in this category. Coincidence?
This could involve the possibility of a self-generating two-gas laser
where one gas is hydrogen and the other is hydrogen in the collapsed
state, formed in situ and making the device efficient due to a UV
emission cascade. This might explain why a hemispherical reactor is
useful (assuming reflectivity is enhanced)
In this regard, this old patent
https://patents.google.com/patent/US4159453A/en
and this article
https://www.hindawi.com/journals/lc/2008/839873/
seem to suggest that something like this possibility has been
considered before... and might explain why the Thermacore project
(with the Navy) was "apparently" canceled, despite the energy anomaly.
Probably worth a deeper look...

There could be one lesson which can be called - GO BIG... but also BEWARE if
you go big.
Perhaps there is something akin to critical mass, which is important for
maximum gain, as in nuclear fission?
If there is a very small but non-zero chance for hydrogen to undergo
certain transitions as it's adsorbed-desorbed from the catalyst
material, then more than critical mass it could be a matter of
critical volume of catalyst through which hydrogen travels before
something occurs.
Perhaps that could explain why resonating systems are sometimes
suggested to work well. They might be able to maximize hydrogen
interaction events (defined as adsorption-desorption cycles) per unit
of time with the catalyst.
Just a simple thought.
