Effect of gas-flow velocity and discharge current on output power in DC axially discharged fast-axial-flow CO laser

Using a prototype of dc axially discharged fast-axial-flow CO laser, the output power of 385 W/m in CW operation has been realized at subroom temperature, together with the output of 165 W/m at room temperature. Both dependence of the gas-flow velocity /spl upsi/ and the discharge current I/sub dis/ on the output power and the effect of /spl upsi/ on the oscillation lines are theoretically analyzed, being well consistent with the experimental results.
