Abstract

Intracavity second harmonic generation of chemical oxygen iodine laser utilizing LiB₃O₅ crystal has been studied. A chemical oxygen iodine laser of which the fundamental maximum output power is 3 W in TEM₀₀ mode with the Cl₂ flow rate of 300 mmol/min is used. Obtained total second harmonic power is a maximum of about 6 W. Therefore, we could estimate that the effective extraction efficiency is 200%. It is thought that the latter is above 100% due to the condition that the output coupling for the fundamental beam is not optimum. And applying the result of a fundamental laser power measurement, the internal conversion efficiency is estimated at 0.29%.
