Comparison of output power stabilities of CO and CO2 lasers

摘要

Abstract: A comparative investigation of the amplitude stability of the power output from sealed-off CO and CO$-2$/ lasers emitting the fundamental spatial mode has been made. It is shown that the use of a CW molecular CO laser emitting simultaneously due to a great number of cascade-coupled vibration-rotational transitions as the coherent radiation source makes it possible to achieve relatively high stability of the output power under conditions of emission of a single main mode without frequency-control facilities.!0
