A conceptual course on LASERs for general education

Abstract

It is important to improve the technological skills and scientific understanding of students who are not pursuing scientific and technological degrees because they are indirectly asked to support science. To be supportive, they need to be able to evaluate scientific information as portrayed by the media. The difficulty is to find a topic which will stimulate and hold their interest in science. One such topic is LASERs. LASERs hold a fascination for students. LASERs are used in a wide array of technological devices and procedures. To understand LASERs requires an understanding of light and optics; of how light interacts with matter and with the structure of matter. Therefore, a course about LASERs can entice students who typically avoid science classes, and in particular physics classes, into taking a physics class, thereby giving us the opportunity to improve their understanding of science, their critical thinking skills and developing their appreciation of basic physics. Such a course can establish a sense of confidence in these students' ability to understand. © ETOP 2009.
