| Abstract: | A segmented flat-plate Blumlein circuit has been used to excite a travelling wave of inversion in pure nitrogen at atmospheric pressure in a 50 cm long discharge channel. UV laser emission in the forward direction was typically 200 times more intense than in the opposite direction. Laser pulse duration as determined by streak photography was 400 psec, whereas peak power was about 1 MW. |
