%X Optical and FTIR spectroscopy was employed to study the properties of 80GeS2-20Ga2S3-CsCl chalcohalide glasses with CsCl additives in a temperature range of 77¨C293 K. It is shown that CsCl content results in the shift of fundamental absorption edge in the visible region. Vibrational bands in FTIR spectra of (80GeS2-20Ga2S3)100£¿£¿£¿§ç(§³sCl)x (x£¿=£¿5, 10, and 15) are identified near 2500 cm£¿1, 3700 cm£¿1,, around 1580 cm£¿1, and a feature at 1100 cm£¿1. Low energy shifts of vibrational frequencies in glasses with a higher amount of CsCl can be caused by possible thermal expansion of the lattice and nanovoid agglomeration formed by CsCl additives in the inner structure of the Ge-Ga-S glass
