Abstract. This short paper describes a proposed new laser using magnetic
pumping. The idea is simple. A ruby laser may just be embedding a laser
ruby rod inside the primary coil of an a/c transformer together with the iron
core. According tocontemporary electromagnetism, electrical energy is trans-
mitted by a current-carrying conductor through the magnetic field around
it. The authors new aether photoelectricity theory offers a different expla-
nation. The energy flow in current-carrying conductors is through aether
apulses , single aether electrical wavelet of one wavelength (the equivalent
of the photon). The flow of such photons (microwave arond 10 µm) within
the conductors is the actual physical mechanism of electrical energy transfer
by metal conductors. There is no magnetism in photoelectricity theory. The
energy currents entering the primary coil of an a/c transformer would jump
the air gap into the iron core. The iron core (when active) conducts the flow
of photons towards the secondary winding. The photons again jump the air
gap and enters into the secondary winding giving rise to the energy current
flowing across the long distance electrical power lines towards its destina-
tion. In the new magnetically pumped ruby laser,the photon flow across the
copper windings and the iron core would have some photons entering into
the embedded ruby rod. Such photons may be able to activate lasing of the
ruby.
1. Introduction
The first laser was operated successfully by Theodore Maiman in 1960 by
shining a high-powered flash lamp on a ruby rod with silver-coated surfaces. A
simple modern version of a ruby laser may be constructed with a synthetic ruby
crystal rod with precise flat end surfaces. One end is coated as a mirror reflect-
ing light from within the crystal. The other end is a semi-transparent mirror that
would allow about 50% of light to pass through. If the light of a strong flashlamp
shines on the crystal rod, the photons entering into the ruby would cause ‘stim-
ulated’ amplification of the photons within the crystal. When sufficient photons
have been produced, a stage would be reached when a coherent laser beam of
red light at 694 nm is produced coming out from the semi-transparent end of
the ruby rod.
This paper proposes a new novel design for powering a laser where laser
pumping is done magnetically. Currently, the most common laser pump en-
ergy is usually provided in the form of light or electric current. There are other
exotic forms including using chemical energy, thermal energy and even nuclear

energy. The new design proposed here employs ‘magnetic pumping’. Such an
approach has not been found mentioned in the current literature on lasers. In
reality,though,the term magnetic pumping is only a misnomer as will be shown.
2. A New Theory Of Energy Transfer In Current-carrying
Conductors
In order to understand magnetic pumping, it is necessary to first discuss the
author’s new theory on a most fundamental issue in
electromagnetism[1]. In contemporary electromagnetism based on Maxwell’s
theory, electrical energy transfer by current carrying-conductors is assumed to
be through the magnetic fields surrounding the conductors. The Poynting theo-
rem is invoked to give the rate of energy transfer. The author is not comfortable
with Maxwell’s theory as it requires the concept of the magnetic field. The con-
cept of the magnetic field should by now be retired; it is a legacy of an anachro-
nism from the early days which assumes that a permanent bar magnet has two
magnetic poles. We now know magnetic poles do not exist. The phenomenon
of magnetism comes from electrical interactions of charged particles when they
have relative motion. The source of ‘magnetic’ forces is still Coulomb electrical
forces.
In the author’s Simple Unified Theory,SUT [2] - an aether theory - an ‘apulse’
is a quantum of light of a single wavelength. All our supposed electromagnetic
waves are waves in the aether of space due to electric polarization of the aether.
No magnetism is involved. Light is electrical aether polarization waves. Apulses
are emitted only through the Bohr’s mechanism when an electron falls from a
higher energy states to a state that is lower. The Bohr’s mechanism is the only
physical method in nature by which light is generated - there is no other. In the
case of nuclear radiations, it would be the equivalent of a nucleon transiting to
a lower state. Light is generated one apulse at a time. The continuous train of
electromagnetic waves as depicted in introduction to Maxwell’s theory does not
exists in reality. It is because light consists only of apulses, each of a single wave-
length, that it appears to have particle property giving rise to the so called ‘wave
particle duality of light’. There is no duality or any ambiguity as to the nature of
light. Light is a wave.
In the author’stheory of photoelectricity without magnetism[1],energy trans-
fer by current-carrying conductors is through absorption and re-emission of
apulses within the conductor; the actual physical mechanism does not involve
any energy supposed to be carried through magnetic fields.
3. How The Transformer Works
With the new photoelectricity theory, a new explanation of how the trans-
former works is found. The schematic of the transformer is shown in Fig 1. In
the case of electricity being generated in a power station, apulses are generated
within the rotor electromagnets due to its motion relative to the copper wind-
ings of the stator - it is apulses generated due to Faraday’s law of electromag-
netic induction. The apluses ‘jump the air gap’ and enters into the stator armature

winding that connects to the primary copper winding of a step-up transformer.
So the initial scenario is an energy current (of aplulses) generated in the power
station that enters into the primary winding of the transformer as depicted in
the figure. The apulses again jump the air gap from the primary windings into
the iron core of the transformer. The permeability of the soft iron, when active,
‘conducts’ apulses which travel towards the secondary winding and enters into
it across the air gap. So the actual physical mechanism of energy transfer across
a transformer is through energy currents - the equivalent of photon currents -
travelling within the conductors and the active soft iron core.
4. A Proposed ‘Magnetically’ Pumped Laser Design
The current literature on lasers does not seem to have any mention of lasers
that derive energy from a magnetic source. The schematic of the proposed de-
sign is shown in Fig 2. The reason why no one has yet proposed such a design is
because the current assumption about the working of the a/c transformer is that
energy transfer is all through the magnetic fields produced by the copper wind-
ings and magnified by the presence of the soft iron core. The current theory
only states that ‘electrical’ energy - somehow - is transferred from input source
as output in the secondary windings.
There is only three forms of energy known in physics, i.e. potential, kinetic
and radiation (light photons). Current electromagnetism does not give the ac-
tual physical form of energy transferred except the generic label ‘electrical’ en-
ergy. There is no suspicion at all that photons may be involved in the working
of the transformer. In the author’s photoelectricity theory, the actual form of en-
ergy is aether apulses (the photon equivalent) that flows within the transformer.
It is this new phenomenon that - if correct - may be the source of pump energy
for lasing medium embedded within the transformer coils.

Figure 2. Magnetically Pumped Laser. The upper pink rod is
the laser rod. The grey rod is the soft iron. When apulses (pho-
tons) jump between transformer windings and the iron core,
some may be absorbed by the laser rod that may result in lasing.
With a lasing medium embedded within the transformer coil together with
the soft iron core, some photons that traverse the air gap would enter the lasing
medium and excites the atoms of the medium. This may finally lead to lasing
giving rise to the emission of a laser beam.
If we assume that the apulses of the energy current in conductors follows
blackbody distribution, at ambient temperature of 20
C, the radiation wave-
length with peak intensity is about 10 µm - in the microwaverange. As to whether
such microwaves could trigger lasing is best left to experiments. There are other
parameters like a/c frequency, transformer voltage or power that may need to be
tuned.
It is uncertain that a dummy load is needed for such a laser to work. If it
works, it may also work without the secondary winding. The setup would then
be just an a/c electromagnet with its polarity reversing periodically. Just to re-
verse the magnetic field in the soft iron requires energy. The small initial energy
current flowing across the copper windings towards the iron core may be suffi-
cient to finally trigger lasing.
5. Conclusion
This new laser design has never been attempted before. If it works, it may
open a large field for laser research. The power of such a laser may only be lim-
ited by the input power source. This design may have the potential to produce
lasers more powerful than any achieved so far.
