This Resource Letter provides a source of information on lasers and some applications revised and updated from Resource Letter MOP‐1 issued more than 16 years ago. It is intended for the use of high school and college teachers both in courses and in guiding students to a broad range of appropriate literature. Articles marked with an asterisk (*) have been selected for publication in an accompanying reprint book. As will be noted the emphasis has been divided between laser history and classroom demonstrations with lasers, since we feel these will be the most valuable articles for readers of this Journal.
