  We report on studies of simultaneous continuous-wave mirrorless lasing on
multiple optical transitions, realized by pumping hot cesium vapor with laser
light resonant with the 6$S_{1/2}\rightarrow 8$P$_{3/2}$ transition. The
multiplicity of decay paths for the excited atoms to their ground state is
responsible for the emergence of lasing in a number of transitions, observed
here in at least seven wavelengths in the infrared (IR), and at two wavelengths
in the blue. We study the properties of the fields generated in the cesium
vapor, such as optical power, directionality and optical linewidth.
