比较了连续激光二极管端面泵浦Nd：GGG（Ca，Mg，Zr）和Nd：YAG激光器的输出特性。在30mW的单条形半导体激光器上，Nd：GGG（Ca，Mg，Zr）和Nd：YAG激光器分别获得了2.4mW和4.6mW的输出功率。对于1瓦的激光二极管阵列，Nd：GGG（Ca，Mg，Zr）激光器的输出功率增加到223 mW，Nd：YAG激光器的输出功率增加到297 mW。Nd：GGG（Ca，Mg，Zr）也由19瓦准连续波激光二极管条泵浦。比较了侧面泵浦和端面泵浦。通过适当的光学器件，端泵几何结构效率更高，输出功率更大，4.3瓦时的斜率效率为47%，而侧泵几何结构的斜率效率为16%，输出功率为2.6瓦。
A Nd:GGG(Ca,Mg,Zr) and a Nd:YAG laser were compared when end-pumped by a continuous-wave laser diode. With a 30-mW single-stripe laser diode, 2.4 mW and 4.6 mW of output power were obtained for the Nd:GGG(Ca,Mg,Zr) and the Nd:YAG laser, respectively. With a 1-watt laser-diode array, the output power increased to 223 mW for the Nd:GGG(Ca,Mg,Zr) and 297 mW for the Nd:YAG laser. The Nd:GGG(Ca,Mg,Zr) was also pumped by a 19-watt quasi-continuous-wave laser-diode bar. Side and end pumping were compared. With the appropriate optics the end-pumped geometry was more efficient and gave more power, 47% slope efficiency with 4.3 watts of output power, compared to side-pumped geometry, 16% slope efficiency with 2.6 watts.
