INVESTIGATION OF THE THRESHOLD OF THE FILAMENTATION AND GENERATION OF SUPERCONTINUUM DEPENDING ON THE CONCENTRATION OF CHLOROPHYLL A PHOTOSYNTHESING PIGMENT IN SEA WATER

摘要

Dependence of filamentation thresholds were investigated as well as filamentation special spread and supercontinuum generation concerning concentration of chlorophyll A photosynthetic pigment. Energy thresholds of filamentation origin were identified in sea water samples. It was observed that rise of chlorophyll A concentration led to rise of filamentation origin threshold. As chlorophyll A concentration rise the efficiency of radiation transformation reduces (radiation of basic harmonic of titan-sapphire laser onto supercontinuum spectrums in wave length range from 420nm to 680 nm).
