Laser can perhaps be characterized as one of the most exciting discoveries of twentieth century. Laser light is a special kind of light possessing unique characteristics. These beams are highly mono chromatic directional, bright and coherent. Department of Physics the College, has set up a laser lab equipped with latest equipments and apparatus useful for postgraduate classes and research. Laser Lab is sponsored by DST (FIST). Department of Physics is very much thankful to Dr. O. P. Kulshrestha the Principal of the College for endorsement and help for setting this Laser lab. The semiconductor laser offers an imposing list of practical applications.
