The patent information in the database of Derwent Innovations Index and the research articles in the INSPEC, which were concerning the laser diode arrays and relevant technology from 2000 to 2007, were analyzed by using of the analysis software tool of Thomson Data Analyzer (TDA). The characteristics of time, country, institution, and technology term of these patents and articles were compared and evaluated in detail. The bibliometrics results would help reveal the trends of development, research fronts, critical technologies and hot topics of research in the relevant R&D field.

Research assessment is an important task for universities, research institutions and government funding agencies. Many assessment methods for basic research rely heavily on the assessment of publications in academica journals. These methods mainly focus on the quantitative comparison of the number of journal articles, however they ignore the quality differences among various journals. This paper presents a new method for qualitative assessment of academic journals by taking into consideration the impact factors of the journals in different disciplines.
