Physical Constants and Optical Quantities

13.1 Fundamental Physical Constants

Physical constants useful in optics are listed in Table 13.1. The values of these constants are those listed by the National Institute of Science and Technology (NIST) available at the time of publication.

13.2 Conversion Quantities

Conversion quantities often used in optics are listed in Table 13.2. The conversion values for the electron volt and the atomic mass unit are the values listed by the NIST available at the time of publication.

In narrow-linewidth tunable laser design and spectroscopy, the units on linewidth and linewidth conversion units are important. From the approach to the uncertainty principle, given in Chapter 3, the following linewidth expressions ...
