    Abstract:

    We have measured the nonlinear refractive index, n(2), of CS(2) at 10.6 microm by observing the onset of whole-beam selffocusing. We find that n(2) is (2.2 +/- 0.7) x 10(-10) esu, which is over an order of magnitude larger than n(2) in the visible.

    Confocal Fluorescence Microscopy

    Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
