The paper describes the design and construction of an intracavity intensity enhanced hot-band CW CO2 laser with the line selected by concave grating. In this laser, using a gas mixture of 13% CO2, 15% N2 and 72% He (volume fraction) at a total pressure of 1 074.9 Pa and a discharge current of 25 mA, more than 100 laser lines are observed from R(56) to P(60) in the regular band 0001-［1000, 0200］Ⅰ,Ⅱ, besides, another 18 lines in 11 μm wavelength region with 9 lines in the 0111-0310 band and 9 lines in the 0111-1110 band, are also observed under the condition of no hot CO2 absorption cell in the cavity. In the experiment, it is found that the laser output power decreases when more helium gas is added to the laser gas mixture. The one-way intrac
