Talk:Four-wave mixing

This page has too narrow a view of four-wave mixing. It not simply an error mechanism in telecommunications. It is a very general class of nonlinear optical phenomena that have many applications.J S Lundeen 00:39, 14 Jun 2005 (UTC)

Redirect or move?
The most common way of writing FWM is with a dash: "Four-wave mixing". This is done e.g. in the classic textbook "Nonlinear Fiber Optics" by G. P. Agrawal. Furthermore, the article on Nonlinear optics has a link to Four-wave mixing, which does not yet exist. I therefore suggest that this article is either moved from Four wave mixing to Four-wave mixing or that a redirect is made from Four-wave mixing to Four wave mixing. I prefer the first alternative, since it is most common to use the dash.

I agree with both of the above statements. FWM is one of the fundamental nonlinear processes, also the use of the phrase 'do the math' give the page an unpolished feel. The page sould also mention the $$\chi^{(3)}$$ from which this process originates. Four-wave mixing is also a more common way of spelling this. Badgerific 19:29, 24 April 2007 (UTC)

Degenerate FWM
Is it for :$$f_{1},f_2$$ or :$$f_1,f_2$$ —The preceding unsigned comment was added by Jishnua (talk • contribs).

needs more explanation
I would like to see more mathematical derivation. What nonlinear equation is used? How does period doubling come out of the equation(s)? Can it be derived using perturbation theory? Danski14(talk) 18:48, 9 March 2012 (UTC)

Working on it. Expect to see it in the next few days to weeks to months :) Quantumavik (talk) 01:39, 17 January 2016 (UTC)
