What is the fundamental difference between nonlinearity of colloidal non-metal and colloidal metal nanoparticles?

One can find the nonlinear refractive indices of non-metal nanoparticles through the maxwell-Garnett formula; however, no one has used this formula to calculate nonlinear refractive indices of...

What is your opinion on magnitude order of higher nonlinear refractive indices of nano-suspensions proposed in virial expansion of exponential model?

According to W. M. Lee, et.al. (see the link) , non-ideal gas model for describing nonlinearity of colloidal nanosuspensions can be explained using the higher order nonlinearities n2, n4, ......

Which optical component has the capability of changing the intensity of a CW laser without any changes in its polarization or any distortion?

A simple idea to change a -fixed intensity- CW laser output intensity is to utilize a polarizer and thus changing polarization will lead to change in its output intensity. If someone needs to keep...
