Laser Theory and Principles
Laser Theory and PrinciplesThe term laser covers a variety of devices, as will be clear from later chapters. While many lasers bear obvious family resemblances to each other, some types are quite distinct. Helium-neon, ion, and carbon dioxide lasers have some important similarities because they all are electrically excited gas lasers, but at first glance they seem to have little in common with semiconductor diode lasers. However, the operation of all lasers relies on certain common physical principles, and it is those principles that will be covered in this chapter.Laser physics is a discipline that draws on many other fields, …
