Abstract

Flash-lamp-pumped laser operation of Nd³⁺:Y₂SiO₅ by use of the Nd^{3+ 4}F_3/2−⁴F_11/2 transition at 1.074 μm is obtained and compared with that from an identically pumped standard-doped Nd³⁺:YAG rod. Higher free-laser performance in Nd³⁺:Y₂SiO₅ is attributed to its higher doping. Approximately 2.5 times more energy in Q-switched pulses is generated in the Nd³⁺:Y₂SiO₅ rod than in the prelase-limited Nd:YAG rod.
