Dual-wavelength infrared multiphoton isotope separation is a topical topic now, having wide foreground, notwithstanding has not wide application in real production for the moment in word and deed.Because of theory unique points and cheap maintenance cost, TEA CO2 Laser is a very ideal illuminant for infrared multiphoton isotope separation, has gotten high separation factor in single-wavelength multiphoton isotope separation experiment. In this paper, the development process of TEA(Transversely Excited Atmospheric pressure) CO2 laser is reviewed, and its application in medicaltreatment, industry processing and interaction photons with materials,especially in infrared multiphoton isotope separation.In turn raises the development of infrared multiphoton isotope separation is reviewed.We use a kind of same space dual-wavelength tuable TEA CO2 laser in the experiment of dual-wavelength infrared multiphoton isotope separation.The length of grating-plane cavity is about 2 meters.The length of discharge chamber is about 2 meters. A mirror which's reflectivity is 80% is placed in one end of the chamber as outgoing mirror, and two glare rasters which's max diffraction efficiency are 95% are placed in the other end. The two rasters are palced in tandem. Axle wire of the one farer to chamber is in the axis of cavity and the other one is not. Their covers are overlaped in sapce.The two rasters can be dealt with as two special mirrors. A parallel planes cavity with small angles maladjusted can be constitutived.Mathematical model which descrips optical field in the cavity of the new style laser can be built by Fresnel -Kirchoff diffraction integral equation.The laser caivty can be regarded as one...
