Is it possible to polarize a laser pointer? Answered

Would it be possible to polarize a laser pointer and still have it retain it's usefulness?


LASERs are polarised, what do you want to do?


True, but here's an interesting tidbit (see <a href="http://www.princetel.com/tutorial_pigtailing.asp">http://www.princetel.com/tutorial_pigtailing.asp</a>).<br /><blockquote> <div> <font color="#666666" face="Arial, Helvetica, sans-serif">[O]nce the beam is coupled into an optical fiber, the SOP [State of Polarization] becomes random unless the fiber is a PM (Polarization Maintaining) fiber.<br /></font></div></blockquote>I didn't know that about optical fibers!<br />

I know it's not dead simple, but I didn't know that.


I vaguely remember that from college...
