Efficiency Considerations of Optical Pumping

Abstract

The thesis deals with the efficiency of optical p i of a ruby laser. The analysis that has bela don Is hOVSVS? spplieabla to any aolUU. state liter. The s all sffioloney of a laser Can be Cale uUtId measures the input electrical cal orgy and the "put p Oso energy. In the dissertation the various factors that determine the effleisney of the laser has been dirai said separately. Chapter I deals with the growth of various Aging schemes with their relative writs and 4►rits. Chapter 11 details the , coupling of the optical energy from the flub tubs to the ruby rod. Also cousibred in this chapter is the design of the cavities for higher •ffieienciis. The efficiency of the ruby rad it"If has been considered In chapters III and IT* An attempt has ter*n mode to calculate the efficiency or ruby rod in bath the absorption bands for disasters between 04 + s to 1.3 case A set of curves has been draim for rod SMCIMr at vsriaus rod diameters. The efficiencies of the various parts of the lee lP system that cava bean considered in the first four chapters have been consolidatod in chapter To to ivalasta the over all efficiency.
