Dither-free stabilization of CO2 lasers for far infrared pumping: A photoacoustic approach
Abstract
A method based on the photoacoustic technique is described for dither-free frequency stabilization of the optical pump in a CH3OH laser operating at 119 (MU)m. Heterodyne measurements on two independently locked FIR lasers indicate excellent long-term frequency and power stability. This stabilization scheme should be applicable to all optically pumped FIR lasants.
