Abstract :
Calculation of the different efficiency parameters of a pulsed solid-state laser is illustrated arithmetically to get efficiency factor and system slope efficiency. The calculated efficiencies are compared with those obtained from experimental work. The design of the pumping chamber is illustrated. Optical resonator losses are got experimentally in details. Different efficiency factors inside laser system are mentioned and how calculate them to get the efficiency factor and system slope efficiency also done. The present system has energy output of 160mJ and pulse width of 100 μ sec for efficiency factor 2.84% and system slope efficiency 1.36%. The combined loss inside resonator is 0.243.
