Self-induced transparency has been observed on a $Q(2)$ -degenerate transition for the first time. Coherent interaction occurs as a short pulse from the $^{2}P_{\frac{1}{2}}F=2\ensuremath{\rightarrow}^{2}P_{\frac{3}{2}}{F}^{\ensuremath{'}}=2$, magnetic dipole transition of the atomic-iodine laser passes through a self-resonant iodine vapor. High transparency and considerable pulse delay at input pulse areas $\ensuremath{\theta}>\ensuremath{\pi}$, and small-pulse splitting at $\ensuremath{\theta}\ensuremath{\simeq}\ensuremath{\pi}$ characterized the phenomena.Self-induced transparency has been observed on a $Q(2)$-degenerate transition for the first time.

Self-induced transparency has been observed for the degenerate, $F=3\ensuremath{\rightarrow}4$, hyperfine component of the 1.315-\ensuremath{\mu}m magnetic dipole transition of atomic iodine, at high optical power levels, up to 50 MW ${\mathrm{cm}}^{\ensuremath{-}2}$. For pulse areas approaching $2\ensuremath{\pi}$, the dynamics of the strong coherent resonant self-focusing which accompanies self-induced transparency have been studied with a streak camera to provide time-dependent analysis of the spatial beam profile.Self-induced transparency has been observed for the degenerate, $F=3\ensuremath{\rightarrow}4$, hyperfine component of the 1.315-\ensuremath{\mu}m magnetic dipole transition of atomic iodine, at high optical power levels, up to 50 MW ${\mathrm{cm}}^{\ensuremath{-}2}$.
