Abstract

A sensitized laser glass which includes a primary lasing dopant and auxiliary dopants which absorb in regions of the flashlamp emission spectrum away from the absorption bans of the primary dopant and transfer the energy absorbed to the primary dopant, thus improving the efficiency and sensitivity of the laser glass. The auxiliary dopant comprises the combination of cerium and chromium as Ce2 O3 and Cr2 O3 and the primary dopant is a rare earth metal, preferably neodymium or erbium as Nd2 O3 or Er2 O3. Th auxiliary dopant consists essentially of 0.1 to 5% by weight Ce2 O3 and 0.025 to 0.1% by weight Cr2 O3, however the preferred concentration of the auxiliary dopant is 2 to 4% by weight Ce2 O3 plus 0.03 to 0.07% by weight Cr2 O3. The experimental data establishes that such auxiliary dopants are particularly suitable for phosphate laser glasses.
