no recommended book? bummer.
Johnathan Ralls
Jan 31, 2017 18:45
in fact i think it'd be beneficial for me to work from the basics up. is there a recommended book to do so?
Johnathan Ralls
Jan 31, 2017 18:42
@JohnRennie could you point me in the direction of some literature? something more directed than bouncing from article to article would be ideal, if you don't mind.

do you know if ionized liquid would be easier to work with then?
Johnathan Ralls
Jan 31, 2017 18:28
how would you ionize the argon for this scenario?
Johnathan Ralls
Jan 31, 2017 18:25
the latter being outside the argon's container
Johnathan Ralls
Jan 31, 2017 18:25
what would be the difference in using an electrode embedded in the container to make contact with the gas as opposed to using an electric field through a coil?
Johnathan Ralls
Jan 31, 2017 18:22
my concern with that is the light refracting from the argons container
Johnathan Ralls
Jan 31, 2017 18:22
would a sealed container of argon be a better choice to pass the light through?
Johnathan Ralls
Jan 31, 2017 18:20
sweet. lets say i'll use an induction coil to create a spark gap. would it be possible to make the generated plasma more dense?
Johnathan Ralls
Jan 31, 2017 18:17
am i being a bother? if not i have another question :D
Johnathan Ralls
Jan 31, 2017 18:15
i understand, was hoping that someone on here would be able to share some experience with the subject for a more interactive learning situation
Johnathan Ralls
Jan 31, 2017 18:14
oh that's fine. i'm not all that interested in light on light interaction, but was curious. if i am able to reproduce a self-focusing effect through a plasma that'd be sufficient
Johnathan Ralls
Jan 31, 2017 18:12
that seems to be the only way i've found so far, but if you know of another that'd be superb information
Johnathan Ralls
Jan 31, 2017 18:11
do you know of any experiments regarding low energy self focusing?
Johnathan Ralls
Jan 31, 2017 18:10
@JohnRennie i feel i need to apologize for the nonsense going on, and would request to steal some of your attention towards an inquiry you may have knowledge about.
Johnathan Ralls
Jan 31, 2017 18:01
there are some pretty interesting phenomena involved there. would you happen to know of any tabletop experiments to attempt low-energy self focusing?

regarding the tension in the room: https://www.youtube.com/watch?v=wvNFiAVl-b0
Johnathan Ralls
Jan 31, 2017 17:51
that is assuming that the same high levels of energy would be required for the interaction/influence while passing through the medium, correct?
Johnathan Ralls
Jan 31, 2017 17:49
thought process is "slow the light, give it more time to shift"
Johnathan Ralls
Jan 31, 2017 17:49
i wonder if passing through a medium with a high refractive index would increase the influence of a surrounding electric field?
Johnathan Ralls
Jan 31, 2017 17:48
bums my gums
Johnathan Ralls
Jan 31, 2017 17:47
collimation?
Johnathan Ralls
Jan 31, 2017 17:47
under what circumstances would it be influenced, and what would the influence be?
Johnathan Ralls
Jan 31, 2017 17:45
is electromagnetic radiation influenced by electric or magnetic fields?
Johnathan Ralls
Jan 19, 2017 17:59
got you with a two. ah snap
Johnathan Ralls
Jan 19, 2017 17:46
oops!

what is function P equal?
Johnathan Ralls
Jan 19, 2017 17:21
@ACuriousMind No teach me
Johnathan Ralls
Jan 19, 2017 17:07
you could try to build one of those ultrasonic "tractor beams"
Johnathan Ralls
Jan 19, 2017 17:04
i bet it's a physics one

@anonymous i've glanced over that article before but with reading more in depth it seems my scenario would fit, with some modifications
Johnathan Ralls
Jan 19, 2017 16:37
@anonymous you are not wrong, but my question is very specific to the type of medium
Johnathan Ralls
Jan 19, 2017 16:37
it goes between a fully reflective surface and a partially reflective surface to "organize" light from a pump in a sense
Johnathan Ralls
Jan 19, 2017 16:36
@anonymous it is a lasing medium, active laser medium.
Johnathan Ralls
Jan 19, 2017 16:32
thank you anonymous
Johnathan Ralls
Jan 19, 2017 16:31
have you studied how a gain medium interacts with light to focus it into a beam?
Johnathan Ralls
Jan 19, 2017 16:30
seems to be the next step for me then haha
Johnathan Ralls
Jan 19, 2017 16:29
how strongly does plasma absorb incoming radiation?
Johnathan Ralls
Jan 19, 2017 16:28
it would be mostly transparent, and as a medium i am unsure how it would interact with a light
Johnathan Ralls
Jan 19, 2017 16:27
what about a plasma
Johnathan Ralls
Jan 19, 2017 16:27
i see why we are talking about different things. in most cases the medium would be solid.
Johnathan Ralls
Jan 19, 2017 16:25
one will take in all energy from the light, the other will not interact at all
Johnathan Ralls
Jan 19, 2017 16:24
again though, not practical
Johnathan Ralls
Jan 19, 2017 16:23
it will either absorb or reflect, but will not allow light to pass through
Johnathan Ralls
Jan 19, 2017 16:23
so how about a partially trasparent medium
Johnathan Ralls
Jan 19, 2017 16:22
but that is not practical
Johnathan Ralls
Jan 19, 2017 16:21
right
