Titanium–Sapphire LaserAs an example of a laser, we describe the titanium–sapphire laser.

A Laser TheoryIn 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.

Driving a Laser OscillationWe 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.

Gaussian Waves and Open ResonatorsA large number of gas and solid state lasers as well as free-electron lasers make use of an open resonator.

Femtosecond LaserMode locking allows a laser with a broad gain bandwidth to generate femtosecond pulses. A mode-locked laser oscillates at the same time on a large number of modes. The fields of all modes are phase-locked to each other.

Gas LasersA 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.
