Spectroscopic properties analysis and laser characteristic simulation of Er:GSGG crystal

测试和分析了Er∶GSGG的吸收光谱和荧光光谱.应用Judd-Ofelt理论计算了Er3+的强度参数、自发辐射跃迁几率、能级寿命、荧光分支比和吸收截面.结果表明,Er3+在4I13/2和4I11/2能级有较长的能级寿命,在966 nm和790 nm处有较大的吸收截面,在2.79 μm处有较大的积分发射截面值,数值模拟了在966 nm泵浦下激光输出特性,在泵浦速率达到一定值时,有较高的量子效率.结果表明Er∶GSGG有望成为2.79 μm波段的理想激光晶体.
