A fluorophosphate-base laser glass having a low non-linear refractive index coefficient and a low liquid phase temperature and comprising a glass composed of 5 to 25% 1/2P2O5 and the remainder of metal fluorides and 0.01 to 3% 1/2Nd2O3 being incorporated into the glass, and more particularly a fluorophosphate-base laser glass comprising 5 to 25% 1/2P2O5, 20 to 35% AlF3, 0 to 5% YF3, 22 to 55% BaF2+SrF2+CaF2+MgF2, 0 to 25% NaF+LiF+KF and 0.01 to 3% 1/2Nd2O3, all % being cationic %.
