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

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.

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

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

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

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,

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.

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

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.
