Introduction to Non Linear Optics 

Best explanation of NLO

In this lecture: •To get laser with particular frequency: Dye laser or use nonlinear optical material. •Conventional light source vs laser •For altering the properties of the material the incident electric field, atleast, should be comparable to the electric field inside the material. •Polarization is introduced. Comment: Polarization and susceptibility are the heart of the non linear optics.

@ 25:00 Here the E-field must be multiplied by the vacuum permittivity too!

From iraq...thks alot sir

Nice Explanation.

Thanks sir

deepesh

te ngerti

Thanks Sir
