Has it been ruled out that the energy anomaly
Perhaps the goal should be to generate beats in the electrode rather than
apply beats to the electrode. If so then the original single laser
experiments of Letts and Craven may have succeeded in doing that, but not
very reliably.
This paper says THz sound waves are now possible.

Yes, the beats in the Hagelstein, Letts, and Cravens experiment are

Were the laser beats in the Hagelstein, Letts & Cravens experiment of this

The way the beats are generated could play role in the generation of
anomalous heat.

So the addition of frequencies requires that the input signal already
contains a non-linear component.
and for entirely linear input the frequencies would not be additive.

The nonlinearity must be attached to the cathode itself because a THz
signal will not go through even 1 micron of electrolyte. In the
Letts-Cravens-Hagelstein experiment, a tiny amount of gold was added to the

Sounds fascinating. May I ask: what are you using as your non-linear

Rumford's used an acoustic model of hot and cold radiation to give equal
existence to hot and cold radiation but the acoustic model has serious
limitations. I think a hole model would still treat hot radiation as
fundamental and cold radiation as only a secondary phenomena.

Sean,
What you are describing is entirely possible. Also, diode lasers can be
driven into modes that produce sidebands just at the threshold of ordinary
output - but it is hard to control the sidebands without an expensive
"loop" receiver and some kind of lock-in control.
Using 2 lasers is prett
Could you use an Optical Parametric Amplifier to create your desired
sidebands? Using one laser as the "signal input" and the other as the
"pump" should give you an output containing sum and difference frequencies
(sidebands, or heterodynes).

Good post, Bob
Because of this effect (Letts/Cravens) and the optical phonon addition of
Hagelstein and the Holmlid work also – it seems clear that laser irradiation
of a metal matrix is perhaps the most promising open avenue for optimizing
LENR gain.
It would be great if THz lasers were a
Laser stimulation of LENR cells is an interesting subject. These
experiments can probe the underlying mechanisms of LENR itself. One of the
things that has not been characterized in the laser stimulation studies is
the sideband noise of the lasers. All oscillators exhibit sideband noise.

I wonder if quanta are made from beat frequencies:

Yes. For instance, if your expectation is based on emission from a stationary
emitter – then “ rotational superradiance” can alter and concentrate
radiation from around the equator of the rapidly spinning emitter while the
polar emission will be subradiant. No gain – simply a shift.
