Pulsed laser deposition
|Abstract:||Isotope enrichment in laser-ablated plume is an interesting phenomenon. In this work, we have compared the boron isotope distribution present in thin films of B₄C that are formed by pulsed laser deposition using nanosecond (ns) and picosecond (ps) pulse Nd-YAG lasers. With the ns laser beam, in the plume we could observe an isotope ratio of ¹⁰B/¹¹B as high as 0.9, but in the film we could hardly see any enrichment. With ps pulsed laser, the maximum value obtained for the ¹⁰B/¹¹B ratio is about 0.29 in the film.|
