| Abstract | ||
| Nickel dye, Bis-(4-Dimethylaminodithobenzil)-Nickel (BDN-I) was used as liquid Q-switch for Nd: YAG laser. Solvent surface tension effect on the Q-switched pulse duration was investigated. Carbon tetra chloride (CCl4), Chloroform (CHCl3), and dioxin (C4H8O2) were used as solvents to BDN-I at molar concentration of 59.52 M/l. The measured Q-switched pulse duration was 60± 2.33, 71± 1.95, and 84± 1.32 nsec respectively. The greatest pulse duration reduction was achieved by using CCl4 which is of the lowest surface tension with respect to other solvents. The study related that to the low ability of electron transfer from this solvent to the dye molecules. | ||
