Free electron laser it is a quite different thing than laser.

When is a laser not a laser? When it is a free electron laser.
Unfortunately, I understand completely.

Laser = "laser - an acronym for light amplification by stimulated emission
of radiation"

Laser rework natural light (radiation).

Antennas produce artifical radiation in the result of the electron
oscillations.

To make the oscillations we use different devices.
LC for radio waves, megatrons for microwaves, claystrons for radar waves and
the Halbach array for the light frequency.

The word "laser" is probably common name for the all atificical light
sources.

Sorry, just my feeble attempt at some comic relief. Guess I should

If the perpetuator of that unethical false inuendo can present any
posting where I said EM waves can bounce off of current or voltage
nodes, I will personally write him a check for $1000. Of course, if he
cannot produce proof of what he asserts, he should post a public
apology.

No, it is not. From answers.com: "Definition: laser - Any of several
devices that emit highly amplified and coherent radiation of one or
more discrete frequencies."

From Wikipedia: "Light Amplification by Stimulated Emission of
Radiation (LASER or laser) is a mechanism for emitting
electromagnetic radiation, typically light or visible light, via the
process of stimulated emission. The emitted laser light is (usually) a
spatially coherent, narrow low-divergence beam, that can be
manipulated with lenses. In laser technology, 'coherent light' denotes
a light source that produces (emits) light of in-step waves of
identical frequency, phase,[1] and polarization. The laser's beam of
coherent light differentiates it from light sources that emit
incoherent light beams, of random phase varying with time and
position."

should we even bring up its close cousin, the MASER? I particularly
like this definition:

"MASER stands for Microwave Amplification by Stimulation Emission of
Radiation. A LASER is a MASER that works with higher frequency photons
in the ultraviolet or visible light spectrum"
from: http://einstein.stanford.edu/content/faqs/maser.html

According to something I read, the MASER, which was introduced while I
was still in high school, was the original idea behind the development
of the LASER. Thanks for your reference which says: "Basically, a man-
made MASER is a device that sets up a series of atoms or molecules and
excites them to generate the chain reaction, or amplification, of
photons."

What??? A MASER is an RF devices. When discussing RF, aren't photons
just a diversion away from "The Truth According to the Great RF
Gurus"? Someone should tell the MASER guys that they are just wasting
their time associating their RF devices with atoms and photons when
they really should be using fields and waves to explain the MASER
phenomena. Good luck on that one. :-)

Hi Miguel,

POWER. *Please observe the distinction as appeals to 100W or "one
second" have no bearing on where you seem to be fixated with quanta
and energy. *Introducing distractions is not very useful. *[I can
appreciate that you are not the source of the distractions.]

I do not confussing wavelengh with quanta!, quantized energy it is

Then quanta is a distraction, or wavelength is.

What sort of human eye we use to see 80 m "light"? :)

Why do you compare 80M to green light? * The more wavelength
appropriate scale would be invisible in the 800nM Infra Red or in the
80nM Ultra Violet. *Green light's correlative would be in the 55.5M
band (tropical SW).

I did not want go out off topic, I claimed quantum mechanics do not
help so much to solve TL related problems and give some reasons for
that.

Indeed, no doubt this [distraction] is attributable to a Texas
[distracting] snake in the grass. *

Quantum mechanics can give a certain perspective and sense of scale,
but [distracting] amateurs shouldn't try that at home or on the
Internet.

I am not an expert in quantum physics and I am not going further
that my elementary physic book examples. Are they wrong? well... then,
I am wrong too :) PSE do not argue with me, I am innocent of charges,
read the references...

The Cosmic Radiation Background has been measured to about 2.76 K,
where the mapping variation (fluctuations of 30 microKelvins) are
within the Energy perturbation (contribution) of our Amateur
transmissions. *

So as to not argue, I firmly agree with you that no one is going to
find any utility in any of this. *But the debate will rage on
heedless.

Hello Richard:

(I am not quoting with "" because I get unpredictable results with
google :) )

You said: "Please observe the distinction as appeals to 100W or "one
second" have no bearing on where you seem to be fixated with quanta
and energy."
I could not translate this sentence, (sometimes your writings are
complicated for me Richard, try Tarzan style or better yet... try as
you were writing to Cheeta! :)
(I handed the sentence to a friend who lives in England and today said
to me that have so many interpretations and did not solve my
problem...)

"Why do you compare 80M to green light?"

Well... I like it! photons born from light, green light it is a
central zone of visible light spectrum, and 80 m is my favourite ex-
novice band...
Look, light has a very rough "texture", light quanta is a very
energetic thing, its "granularity" it is high and we easily perceive
its quantic nature, 80 m energy instead has a very, very "soft"
texture, 10^8 time softer than green light, and we can not measure its
"granularity" with our instruments. Think of a 1000 kg car smashing
against your car at 100 km/h, now think of a mosquito (10 mg) smashing
against your windshield at the same speed.. well if the one green
light quantum had the cinetc energy of a 1000 kg thrown against your
car, 80 m quantum would have the mosquito energy! It is a really good
example... you should congratulate me for that formidable approach!!
no?, hi hi

Physicists said that we can better perceive energy glanularity at
lower temperatures and they say we have classic behaviour when hv
kT, well... at 1 K, kT it is 6000 times bigger than 80 m hv, a very
classic oscilator indeed!, at 293 K ambient temperature I think we can
not appreciate quantized nature of RF waves!, (at least with my Bird
43) :)

I have a question too, please tell me (I am very curious): why you
take every opportunity to bite (sting?) my friend Cecil, ah? ;). I
read carefully Cecil writings and I do not find flawings in his
affirmations; usually he is very precise and scholar on this matters,
sometimes he has an occasional forgivable habit, such his predilection
for photons and polished glass things, but I think he has not so
"distractive", usually I understand wiich is "his point" to bring
another physics areas on the table... I think often we have a little
stubborn too :D

73, and thank you very much for your company - Miguel - LU6ETJ

Laser and maser reworks the light produced by atoms or molecules.

In the Halbach array no atoms or molecules.
There are working only the electrons in vacuum. Like in transmitters,
megatrons and claystrons.

Is a MASER actually a LASER?
