An intracavity laser spectrometer at F+2 color centers in a lamp-pumped LiF crystal has been put in operation for the first time. It operates at a room temperature. Active centers are pumped with the help of a luminescent transformer at a Rhodamine 6G solution in ethyl alcohol. Quasicontinuous lasing has been obtained in a region 10450-10580 cm-1 with a duration up to 20 μs, which has provided for a threshold absorption sensitivity of 5 * 10-1 cm-1.
