Optics, Photonics & Laser

Lasers and Nonlinear Optics

It is the study of phenomenon which takes place as the consequence of the changes in the optical properties of a material system in the presence of light. Nonlinearity is typically observed at high intensities (for example those which are generated by lasers). Nonlinear optics provides the key technologies which helps in providing radiation sources in various wavelength ranges from x-rays to terahertz. These are basically used in combination with laser technology.
