Function Transformation of Nanosecond Laser Flash Photolysis Apparatus The determining method of the second order non-lineal coefficient for non-lineal organic materials

Laser flash photolysis apparatus at nanosecond scale can be applied to study the dynamical process for organic photochemistry, proteolysis, transient emission and absorption of light. On the basis of not changing the arrangement and setup, the determining method of the second order non-lineal coefficient has been established for non-lineal organic materials through design and transformation, its arbitration measurement was carried out for the state 863 specialist committee.
