Welcome To Non–Linear Optics and LASER Spectroscopy Laboratory
Overview:
Nonlinear Optics and
Laser Spectroscopy laboratory started functioning immediately after the
completion of construction of the first phase for Center for Advanced Research
in Sciences (CARS), in early 2005. The main reason behind the establishment of
this laboratory was exactly the same to the reason behind the establishment of
the center (CARS) that was to create advanced research facilities to pursue
research in the frontiers of science and to provide the faculty members access
to these facilities. Amazing advances are being made by using high power
ultra-short laser pulses in spectroscopy. Because of the progress mentioned
above and an increased sophistication of research in lasers and quantum optics
for last few decades and in particular the lack of state of the art technology
equipment, which became very expensive for the university to provide to its
researchers in different departments or in individual groups. A nonlinear
optics and laser spectroscopy lab was established in the center, to do the
advance research in the field of lasers and modern optics.
