通过亚皮秒 (450 fs) KrF 激光沉积，从晶体 Er: YAG 和 Er: YAP 激光棒中生长出掺杂 Er 的 YAG (Y3Al5O12) 和 YAP (YAlO3) 薄膜。研究了激光功率密度、衬底温度、靶材-衬底距离和沉积环境气氛（真空或氧气）的影响。给出了形态、成分、结构和发光分析的结果。即使在较低的衬底温度下也可以获得晶体薄膜。所有样品均观察到与 Er+3 离子相对应的发光。
Thin YAG (Y3Al5O12) and YAP (YAlO3) films doped with Er content were grown by sub-picosecond (450 fs) KrF laser deposition from crystalline Er: YAG and Er: YAP laser rods. The influence of laser power density, substrate temperature, target- substrate distance and deposition ambient atmosphere (vacuum or oxygen) was studied. Results of morphological, compositional, structural and luminescence analysis are presented. Crystalline films have been obtained even for low substrate temperature. Luminescence corresponding to Er+3 ions was observed for all the samples.
