在经过标定的ＮｄＹＡＧ激光器产生的超短红外脉冲激光激励下，采用双光束入射、单脉冲测量方案，利用可见光条纹相机研究了电子俘获材料ＣａＳＥｕ，Ｓｍ的红外上转换发光情况，结果表明：在λ＝１．０６４μｍ，ＦＷＨＭ＝１９．２ｐｓ的红外脉冲激光作用下，这类材料红外上转换发光的ＦＷＨＭ优于１４．３ｐｓ。
The infrared upconversion luminescence of electron capture material CaSEu and Sm was studied by using double-beam incident and single-pulse measurement under the excitation of ultra-short infrared pulsed laser generated by a calibrated NdYAG laser. The results show that the λ / = 1.064μm and FWHM = 19.2ps, the FWHM of infrared upconversion luminescence of these materials is better than 14.3ps.
