Abstract:An unconventional way of generating laser light with semiconductor structures is to irradiate them with a high energy electron beam of sufficiently high current density. Electron beam pumping thus offers the possibility to scan the exciting electron beam along a bar of semiconductor laser material, moving the lasing spot with the swiftness of the electron beam. This paper describes such a laser scanner. Laser scanners find wide application in laser printers, bar code readers etc. Most of these scanners are lim… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
