The refractive indices n, power absorption constant α (cm−1), and percent transmission T of YAG and YLF were measured in the 10–100-cm−1 range. Only the percent transmission T of thin samples of the elpasolite hexachloride Cs2NaDyCl6 and hexafluoride Rb2NaYF6 was measured in the 10–400-cm−1 range since T was 2–3%. A brief discussion of the far-infrared (FIR) laser possibilities of rare-earth doped crystals is presented.
