Abstract

The invention relates to aluminoborosilicate-based glasses suitable for use as a solid laser medium. In particular, these aluminoborosilicate-based laser glasses exhibit broad emission bandwidths of rare earth lasing ions. Although not entirely understood, the broadening of the emission bandwidth is believed to be achieved by the presence of significant amounts of lanthanide ions in the glass matrix. In addition, because of the high values of Young's modulus, fracture toughness and hardness, the rare earth aluminoborosilicate glass system according to the invention is also suitable as transparent armor window material.
