Abstract

The Stark effect modulations with Doppler broadening have been analyzed by semiclassical theory. The absorption coefficient and modulating depth of Stark effect system have been derived by density matrix method. Modulation characteristics between line of the isotropic ¹³CO₂ laser at 10.784 micrometers and as Q transition of NH₃ molecular have been researched. When modulating frequency is 1MHz, modulating frequency is 1MHz, modulating depth reaches 33 percent. An isotopic ¹³CO₂ laser, which outputs 4W and has 25 lines of spectrum, was fabricated. Instability of laser intensity is less than 1 percent.
