Abstract
We have studied nine laser transitions in Ba vapor at wavelengths
between 1.13 and 3.05 micrometer. Three of these laser lines have not
been reported previously. The relative intensities of the four strongest
transitions (1.13, 1.50, 2.55, and 2.92 micrometer) vary with buffer gas pressure,
suggesting that collisional deexcitation of the 6p 1^P_1 state occurs
at higher pressure and is the main mechanism populating the upper
states of the 2.55 and 2.33 micrometer lines.
