Abstract
Refraction index dispersion in Tl1–xAgxGaSe2 (0 ≤ x ≤ 0.25) crystals is investigated by studying their intrinsic interference. It is shown that there are domains with anomalous dispersion in the investigated crystals at wavelengths slightly exceeding those corresponding to exciton peaks. It is established that excitons in the crystals can be detected from their intrinsic interference at room temperature. In addition, modulation of interference patterns is observed, and a possible explanation of this phenomenon is proposed.
