We investigated the fluorescence and lasing characteristics of chromium- doped forsterite with high chromium concentration of 0.13-0.14 mol%. It was shown that the 0.13-0.14 mol% chromium sample has about threefold stronger intensity of the fluorescence extending from 1050 nm to 1400 nm, which causes laser oscillation, than the 0.04-0.06 mol% chromium sample which is usually used. The strong polarization of fluorescence extending from 1050 nm to 1400 nm was observed. Laser oscillation was achieved by using the 0.13-0.14 mol% chromium sample whose size was only 5 X 5 X 5 mm3.
