Read More The co-words analysis, as a scientometric method, helps us to discover the conceptual relationships between scientific texts and application of such relationships as a means to demonstrate important links that may be difficult to discover in other ways. This article is intended to use an analytical approach and identify research areas and to reveal the intellectual structure of knowledge in laser researches in biomedicine literature during 2009-2018. In this descriptive-analytical study with a scientometric approach, the data about laser were retrieved from PubMed in MEDINE format, including 7,682 articles with 18,227 keywords. By using co-word analysis, clustering methods, and strategic diagram; the data were analyzed with the help of SPSS 20, UcInet, and VOSviewer software. This study found that a steady growth could be seen on the laser research and 19.47% of publications are found in 5 journals. The most frequent keywords in the field of laser have been “lasers, solid-‎state”, “laser therapy”, “lasers, ‎excimer”, etc. The results of cluster analysis shaped the concepts of laser in 7 clusters. The cluster “laser, excimer” was well developed and it plays an effective role. In contrast, “Photo ‎chemotherapy”, “skin diseases with Emphasis ‎on Lasers, gas”, “Laser Effects”, “Laser dentistry “and “Corneal Surgery, Laser” were relatively immature, which necessitates potential research space for future study. This research used co-word networks that indicate the important links between keywords of research areas. Disclosing the thorough context of issues which were encountered at the time of investigating, these networks will be used in locating knowledge gaps. Majority of research approaches include treatments or therapeutic aspects of laser in ophthalmology. The lack of some topics such as cardiology, oncology, optogenetics etc. shows that they have not been considered. Moreover, nevertheless of the practice site, application, or system in use, there is the goal of ‎making and keeping a laser-safe environment for the staff, the user, and patient. These subjects have not been sufficiently considered.
