Newton, Prisms, and the "Opticks" of Tunable Lasers
F. J. Duarte
Newton's contributions to the understanding of refraction and dispersion were central to the design of prism spectrometers; his reflection telescope introduced the basic principles of modern observational telescopes. What is not generally recognized, however, is that Newton's original prismatic configurations also laid the foundations for some of the principles applied today in the optics of tunable lasers. This little-known fact is the focus of this article.
