Hot CO/sub 2/ was used to check theoretical understanding by using one-nanosecond pulses. The results reported are in relatively good agreement with theory. The experimental setup consisted of a one nanosecond duration 1/2 millijoule switched-out pulse directed through two heated pyrex cells filled with CO/sub 2/ and fitted with NaCl windows at Brewster's angle. The cells were 190 cm long of which 160 cm were heated to 300 +- 10/sup 0/C for a total heated path of 320 cm. Results are shown. They verify previous knowledge that hot CO/sub 2/ operating as a linear filter is not for one nanosecond …

Description
Hot CO/sub 2/ was used to check theoretical understanding by using one-nanosecond pulses. The results reported are in relatively good agreement with theory. The experimental setup consisted of a one nanosecond duration 1/2 millijoule switched-out pulse directed through two heated pyrex cells filled with CO/sub 2/ and fitted with NaCl windows at Brewster's angle. The cells were 190 cm long of which 160 cm were heated to 300 +- 10/sup 0/C for a total heated path of 320 cm. Results are shown. They verify previous knowledge that hot CO/sub 2/ operating as a linear filter is not for one nanosecond systems, i.e., good baseline rejection and lack of ringing are incompatible for one nanosecond pulse durations. Some preliminary data are given on an attempt to compress a one nanosecond switched-out pulse by a factor of 6 by saturating SF/sub 6/ in a short cell. (MHR)
