Kapanadze Cousin - DALLY FREE ENERGY

Ok. I'll make some experiments on this, and let you know if I get some different effects.
Thanks for the clues...

Ideally yes, but any perpendicular component will suffice, even the perpendicular components of two bucking fields, such as created by two parallel coaxial coils (in bucking mode) or two repelling magnets.
Unfortunately yes, and don't forget about the requirement for field homogeneity, too. The latter is needed to keep the same operating frequency throughout the whole volume of the Gain Medium

Fortunately the nanopulses come to the rescue with the "Shotgun Approach", because short pulses are composed of multiple frequencies that can stimulate the Gain Medium at different frequencies simultaneously. Multiple operating frequencies are the result of inhomogeneities in the perpendicular components of the field occuring throughout the volume of the Gain Media.

Because of Mr. Fourier - the narrower the pulse is, the higher the probability that it will hit the bullseye.

To stimulate the Gain Medium at different frequencies simultaneously, one needs not only short pulses but also a low repetition rate of these pulses. Alternatively, the short pulses at higher repetition rate have to be frequency modulated. All this is explained in the invaluable resource provided to the community by William J. McFreey (PJKBook, chapter 3, page 3-135).

Notice that the Shotgun Approach is very inefficient.

If you ever hit the bullseye then you might want to switch to a Machine Gun Approach, such as the HF Frequency Modulation around the frequency of interest or LF Amplitude Modulation of the perpendicular bias field.

A Sniper Approach would require a perfectly homogeneous field and a single stimulation frequency, but it would be extremely hard to tune and maintain. Next to impossible if intermodulation effects are considered.

There is also the issue of confinement which is supposed to prevent the decay of the reaction in the Gain Medium.  This confinement is analogous to the reflectors (silvered mirrors) at the ends of laser tubes, which confine the internally generated photons.
The ideal case of magnetic confinement requires a perpendicular field inside of the Gain Medium and parallel field outside of it (at least on one side - ideally both).

Somebody in the long TK thread suggested that the easiest way to accomplish that field geometry is to put permeable disks for flux guiding, at the end of the stimulating coils/magnets, and the Gain Media adjacent to those disks.
...and conceal those disks in a green can, of course

This confinement strategy forms a spool-like shape, which is illustrated below (BTW: the simulation program has a bug regarding the arrow directions)

To stimulate the Gain Medium at different frequencies simultaneously, one needs not only short pulses but also a low repetition rate of these pulses.

Yes, of course.
The Fourier analysis illustrated somewhere at the beginning of this thread nicely illustrates that low duty cycles (low pulse repetition frequencies) yield the broadest spectrum of component frequencies for the same pulse widths.

[yfree]

Yes, of course.
The Fourier analysis illustrated somewhere at the beginning of this thread nicely illustrates that low duty cycles (low pulse repetition frequencies) yield the broadest spectrum of component frequencies.

Low duty cycle is not the same as low pulse repetition frequency.
The broadest spectrum of component frequencies is not what is necessarily needed, but rather a dense spectrum of frequencies in a band of frequencies. However, frequency modulated sine-wave, not the sharpest pulses, is always more efficient.
