This patents discloses a pulsed carbon dioxide laser that eliminates the nitrogen tail on the pulse by placing a Brewster angle absorption cell inside the optical cavity of the laser. This Brewster angle absorption cell contains a gas which exhibits a preferential absorption in the 10 micron spectral regime. This preferential absorption causes the laser to lase in the 9.6 micron regime which allows for easier harmonic generation and elimination of the nitrogen tail. jhd
