Authors: Rajendiran, P.

Abstract: Identifies various bibliometric indicators of articles published by the Indian researchers in the field of laser science and technology during the period 1995-2005. The Scopus - the indexing/abstracting online database is the main source for this study. The bibliometric techniques, such as Bradford's law, Lotka's law and the Subramanyam formula were employed respectively to measure quantitative distribution of literature in sources/journals, author productivity, and the degree of collaboration among authors. The study found that the literature growth has steadily increased and the growth rate over the period of time was 22.436 articles per year. Of the total literature, 97.32 % appeared as research articles. Literature was found to be published in eight different disciplines, and the percentage of multi-disciplinary articles was 18.93. The log-log plot drawn for distribution of literature in various sources/journals fits the typical Bradford S-shaped curve. The study identified 20 core sources and 23 core journals. It was found that majority of authors contributed only one article (65.04%), which is larger than the 60% of original Lotka's data. The degree of collaboration among authors is 0.94. The average length of an article is 7.09.
