Pump absorption and losses of the optically pumped FIR waveguide laser
Abstract
The relations between pump absorption losses and the waveguide cavity configuration parameters are calculated based on the Gaussian beam transformation in the plane-parallel resonator. It can be seen from the calculations that the pump loss due to the pump beam diffraction on the wall of the waveguide is generally more than 57 percent, and that it is the main source that leads to a low pump absorption.
