Among several laser applications, nonlinear optical phenomena have emerged as a new area of research. Nonlinear optics of low dimensional systems such as quantum dots (0D), carbon nano tubes (1D) and graphene derivatives (2D) has been under intense scrutiny. In the present manuscript we present some of our research work in these topics carried out with a simple technique of z-scan. This technique is useful for the studies of novel materials and can be replicated in a laboratory that has a pulsed (ns or shorter duration) laser facility.
