光合色素分子吸附膜的非线性增强效应

Nonlinear enhancement effect of absorbed layers of photosynthetic pigment molecules

吸附在光学表面上的细菌叶绿素和藻兰素生物分子膜.在基波(λ=1.06μm)激光作用下,观察到谐波效应.文中对藻兰素只产生三次谐波而不产生二次谐波做了分析.

Laser beam at λ=1.06 μm was used as fundamental wave to irradiate on the adsorbed layers of the photosynthetic pigment molecules (baoteriochlorophyll and phycocyanin) on the optical surface. The harmonic generation is observed. It is discussed that the adsorbed layer of phyoooyanin can generate only third harmonic (THG) not second harmonic (SHG).
