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 is disclosed. This Brewster angle absorption cell contains a gas which exhibits a preferential absorption in the 10 micrometer spectral regime. This preferential absorption causes the laser to lase in the 9.6 micrometer regime which allows for easier harmonic generation and elimination of the nitrogen tail.
