can be divided into groups according to different criteria:
The state of matter of the active
medium: solid, liquid, gas, or plasma.

wavelength: visible spectrum, Infra-Red (IR) spectrum,
The excitation (pumping) method
of the active medium: Optic pumping, Electric pumping,
The characteristics of the radiation
emitted from the laser.
of energy levels which participate in the lasing process.
