Abstract
Large fluctuations of output power have been observed above a certain level of the radiation power accumulated inside the laser cavity. These fluctuations can be effectively suppressed by circulating the gas mixture through an unexcited region between the active medium and one of the cavity mirrors, or by removing CO2 molecules from the gas mixture in the unexcited region. Experimental evidence indicates that the fluctuations are due to the absorption of intracavity radiation by the CO2 molecules contained in that region.Keywords
