Abstract

The design of laser spectrophotometer with narrow-line tunable alexandrite laser and 30-m multipath gas cell is described. This spectrophotometer was applied to study the nonselective absorption of H₂O vapor within 0.72 - 0.78 micrometers range. The measured value of nonselective absorption coefficient was found to be equal of approximately equals 3 (DOT) 10^-8 cm^-1.
