Laser discussion

Recommended Posts

You know, I got a theory about lazer beams that we could make them by condensing protons into bullets. If we get to a quark, and condense a couple million of them into a bullet? I didn't really think about quarks being in protons- and that they're little molecular charges.

Im not even going to Try and address this post, but I think youll find molecules are Much larger than subatomic particles!

Lasers are polarized photons. Not made of protons. We're talking apples and oranges here.

are lasers polarised? i thought they were just coherent i thought to get a polarized bean you needed a polarizing filter?

maybe it depends on the type of laser?

Iv used gas and diode lasers and all the diode types were polarised, I never tested on the gas though.

Coherent and highly directional, but not polarized (at least for penlight lasers and such).

all laser pens are affected by Polarising filters to my finding.

I use a Cokin A160 filter and have a Red laser that can be blocked entirely by rotating this and then allowed to pass by rotating it further.

some pens arent entirely blocked though.

It depends on the LASER whether the light is polarised or not, it is not a requirement.

Most lasers are indeed polarized, though as Klaynos has noted, it is not a requirement.

Laser diodes are polarized; IIRC the gain medium doesn't support one of the orientations. Other systems include a Brewster plate to suppress the competing mode.

i never knew that about lasers, oh well, learn something new everyday here and all that.

If the polarity was controlled, then what? I now notice about the subatomic particles and such but what about the LASER? is it in any way possible? This is a post about modern warfare apparently, but is this in some ways possible? Apparently yes as you have been stating. Now I know, thank you, and really, I'm about ten so if you coould include more detailed answers about theese things I would appreciate it.

Lasers do not shoot protons, which are nuclear particles. They shoot photons, which are particles of light. (This was pointed out very early in the thread.)

Perhaps you'd like to restate the question. Are you asking if lasers can be used as weapons?

Thats what I thought! I asked my dad if protons were light, and he said it was a byproduct, so I asked him what light was called, and he said he didn't know, so here I am calling photons protons.
