In 1973 i build my first CO2 waveguide laser that produce 10 W cw.
The laser emission is polarised vertically with a beam diameter of 1.5 mm. The resonator is confocal and the mirror are mounted on 3 invar rods.
This laser can be pulsed with high voltage capacitor discharge. The discharge tube is in aluminium oxide Al2O3 .The cooling is done with deionised water.
