Classroom experiments on laser physics

Paper Abstract

Lasers have made the revolution in the modern optical technologies but there is hardly any efforts to take up the basic understanding of laser Physics via laboratory classes at graduate and undergraduate level. In this paper, a simple experiment for studying the life time of the upper laser level under lasing condition, the relaxation oscillations, measurement of threshold current and variation of laser power as a function of current in a laser diode is presented. The experiment utilizes the readily available low cost components, a key chain laser and some of the electronics instrument normally available at any undergraduate laboratory of science and engineering department.
