Abstract
Methods based on the Stark effect are described for dither-free frequency stabilization of the optically pumped submm laser. The CO2 pump laser was stabilized using a Stark Lamb dip signal of the submm lasant in an external Stark cell. An estimated frequency stability (Δf/f) better than ±1.4×10−8, for one hour recording, was obtained by this method. The frequency of the submm laser was stabilized using the d.c. and a.c. Stark effects for a metal-dielectric rectangular waveguide laser. An estimated frequency stability of ±6×10−8 was obtained for 119 μm line of CH3OH laser for one hour recording.
