报道了脉冲激光沉积生长一系列石榴石晶体的方法。由于制造工艺的优化，现在可以生长出光学质量接近于块体材料的薄膜。为了证明这一点，我们给出了斜率效率为70%、输出功率为-16W的Yb：YAG薄膜的激光性能。此外，我们还首次实现了激光质量为Yb：GGG和Yb：YGG的脉冲激光沉积。这两种镓石榴石的激光性能达到了瓦级，并讨论了进一步提高性能的途径和潜在的应用。
The growth of a range of crystal garnets by pulsed laser deposition is presented. As a result of optimization of the fabrication process, films can now be grown with optical quality approaching that of bulk material. To demonstrate this, we present laser performance from a Yb:YAG film with 70% slope efficiency and >16 W of output power. In addition, we present the first pulsed laser deposition of laser quality Yb:GGG and Yb:YGG. Watt-level laser performance is achieved for these two gallium garnets and routes to further performance improvements and potential applications of these films are discussed.
