Abstract
Self-induced transparency is reported for circularly polarized light in the line of a 30 ppm ruby () at 1.7 K in a magnetic field of . In such a field and temperature, a 30 ppm ruby is in the so-called superhyperfine limit resulting in a long phase memory time, , and a thousand-fold slower pulse propagation velocity of was observed, compared to the measured in the first observation of self-induced transparency (SIT) years ago, that employed a ruby with a 500 ppm chromium concentration in zero field and at 4.2 K. To date, this is the slowest pulse propagation ever observed in a SIT experiment.
