Abstract:
In this thesis we have presented some aspects of the nonlinear dynamics of
Nd:YAG lasers including synchronization, Hopf bifurcation, chaos control
and delay induced multistability.We have chosen diode pumped Nd:YAG
laser with intracavity KTP crystal operating with two mode and three mode
output as our model system.Different types of orientation for the laser cavity
modes were considered to carry out the studies. For laser operating with two
mode output we have chosen the modes as having parallel polarization and
perpendicular polarization. For laser having three mode output, we have
chosen them as two modes polarized parallel to each other while the third
mode polarized orthogonal to them.

Abstract:
We report the experimental observation of subcritical Hopf bifurcation and the existence of non-oscillating “windows” in the dynamics of a Ne-Nd hollow cathode discharge current as the control parameter.
