Radial and time-resolved measurement of cuprous bromide concentration in a Cu-HBr laser

Radial and time-resolved measurements of cuprous bromide (CuBr) molecules have been performed in the Cu-HBr laser for the first time. The results show that under lasing conditions as well as under oven conditions the concentration of CuBr is very small (<10/sup 13/ molecules/cm/sup 3/) in the laser plasma tube.
