摘要
实验观察表明，非生物体有消荧光现象，生物体也有消荧光现象。它是激光与物体表面非线性相互作用的结果。植物叶片的消荧光现象是一个多光子过程，并且荧光消失过程伴随二次谐波产生。荧光消失过程中，荧光能量部分地转换为二次谐波信号，经粗略计算，转换效率大约为２．２％。
Many experimental observationsshow that the fluorescence-disappearance phe-nomenon happens at somatic body,biobody,and other materials. This phenomenon is dueto the nonlinear interaction between their sur-face and the laser. Experimental study on theleaflet of plant shows that fluorescence- disap-pearance phenomenon is a multiphoton pro-cess,and is accompanied with second harmo-nic generation,During fluorescence- disap-pearance process,the fluorescence energy istransfered into second harmonic signal partial-ly,after roughly counted,the transfer coeffi-cient is about 2.2%.
