Er:YAP具有3μm的大发射截面，是Er:YAG的三倍大。 高掺杂的Er:YAP可以发射2.73µm 波长的激光，低掺杂的Er：YAP晶体可以发射1.66µm 的激光。Er:YAP晶体的发射光谱和激发光谱显示出在人眼安全区域内有较宽的发射带，其峰值在1545nm和1608nm附近，并且泵浦带适用于常见的800nm和970nm二极管激光器，这表明YAP是一种 1.5μm人眼安全范围内的二极管泵浦激光器的候选晶体。
与YAG相比，钇钙钛矿铝（YAP）由于具有较高的导热率（～13.3 W m-1 K-1），良好的机械性能和较低的光子能量，有望成为有效激光发射的基质材料。 而且，Er:YAP是最有前途的激光材料之一，可以提供高功率的中红外相干光束。
