<title>Effect of an external magnetic field on the output power of a copper bromide laser</title>

Abstract

An experiment for increasing the relaxation rate of the lower laser level of energy in a CuBr laser has been performed by applying a variable axial external magnetic field (EMF). A CuBr laser was employed. The effect of an axial EMF on the output power of the laser under different charging voltages and buffer gas pressures has been studied. We demonstrate that by applying an axial EMF, the output power of the laser can be optimized. The increase of the buffer gas pressure has a negative effect on this optimization. Simulation of the excitation electric field also shows that, by applying an EMF, attenuation of the electric field in radial direction and the delay between the electric field on the tube axis and the tube wall decreases.
