Continuous Wave Operation

Operation mode of a Laser with continuous Light emission.

Continuous-wave operation of a laser means that the laser is continuously pumped and continuously emits light. The Emission can occur in a single Resonator mode or on multiple modes.In continuous-wave operation, some lasers exhibit too strong heating of the Gain medium. The heating can then be reduced by quasi-continuous-wave operation, where the pump power is only switched on for limited time intervals. Some lasers are called continuous-wave mode-locked. This means that the laser is mode-locked, and the pulse Energy is constant, there is no Q-switched mode locking. Despite the emission of pulses, mode locking can be considered as a kind of continuous-wave operation in the sense that the resonator Modes are excited with constant powers.
