Dimitris Drikakis,William RiderIn this chapter, we present simple laser equations describing the dynamics of laser oscillation. The equations are coupled differential equations of first order relating the populations of the laser levels and the photon density.

前面

https://doi.org/10.1007/b137615We investigate the role of electric polarization of a laser medium in order to obtain further insight into dynamical processes occurring in a laser. The reader, who does not wish to interrupt the description of a laser and its operation, may skip over this chapter.

Centered High-Resolution MethodsIn this chapter, we describe techniques used to operate lasers as continuous wave lasers or as pulsed lasers — in the next chapter we will treat femtosecond lasers.

https://doi.org/10.1007/b137615A gas laser contains atoms or molecules. Stimulated transitions occur in atoms between electronic states and in molecules between rotational, vibrational, or electronic states. We describe various gas discharge lasers: helium–neon laser; metal vapor laser; argon ion laser; excimer laser; nitrogen laser; CO. laser; optically pumped gas lasers.
