The plate can be used as an optical phase modulator.<\/li>\n<li class=\"no-indent\">An anisotropic crystal whose refractive indices can be varied serves as a wave retarder of controllable retardation; it may be used to change the polarization properties of light.<\/li>\n<li class=\"no-indent\" style=\"text-align: justify\">A wave retarder placed between two crossed polarizers gives rise to transmitted light whose intensity is dependent on the phase retardation. The transmittance of the device is therefore electrically controllable, so that it can be used as an optical intensity modulator or an optical switch.<\/li>\n<\/ul>\n<p style=\"text-align: justify\">These are useful components for optical communication and optical signal-processing applications.<\/p>\n<p style=\"text-align: justify\">\n<p class=\"no-indent\" style=\"text-align: justify\"><strong>Summary<\/strong><\/p>\n<ul>\n<li class=\"no-indent\" style=\"text-align: justify\">In SHG process, when an incident light passes through a non-linear medium, new photons of frequency doubled the incident frequency gets generated.<\/li>\n<li class=\"no-indent\" style=\"text-align: justify\">Application of SHG finds its recognition as an important mode of microscopy used in biological researchers to probe the electrical conductivity of nerve cells.<\/li>\n<li class=\"no-indent\" style=\"text-align: justify\">When the number of molecules increases, the linearity curve diverges beyond the critical displacement showing nonlinearity in its quadratic potential displacement curve and hence the atoms get ionized.<\/li>\n<li class=\"no-indent\" style=\"text-align: justify\">The general formulation of susceptibility gives us the units of 2nd, 3rd order \u2026\u2026\u2026.. susceptibilities.<\/li>\n<li class=\"no-indent\" style=\"text-align: justify\">The unit of 2nd order susceptibility is<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-92\" src=\"http:\/\/msp11.epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/sites\/112\/2018\/12\/01-3.png\" alt=\"\" width=\"149\" height=\"74\" srcset=\"https:\/\/ebooks.inflibnet.ac.in\/msp11\/wp-content\/uploads\/sites\/112\/2018\/12\/01-3.png 149w, https:\/\/ebooks.inflibnet.ac.in\/msp11\/wp-content\/uploads\/sites\/112\/2018\/12\/01-3-65x32.png 65w\" sizes=\"auto, (max-width: 149px) 100vw, 149px\" \/><\/p>\n<table>\n<tbody>\n<tr>\n<td><strong>you can view video on Formulation of SHG using Classical Harmonic Oscillator<\/strong><\/td>\n<td><a href=\"https:\/\/youtu.be\/8Af0UTC5le8\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-120\" src=\"http:\/\/epgpbooks.inflibnet.ac.in\/wp-content\/uploads\/2018\/11\/download.png\" alt=\"\" width=\"36\" height=\"36\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p class=\"no-indent\"><strong>References<\/strong><\/p>\n<p class=\"no-indent\">1.R.W.
