What is a continuous wave laser mode?

In the context of laser technology, a continuous wave (CW) laser mode refers to a laser that emits light at a constant power level without interruption. This mode of operation ensures a steady output, which is critical for various applications, including surgical and therapeutic procedures in periodontology.

By providing a continuous beam of light, these lasers can deliver consistent energy to tissues, allowing for precise and controlled treatments. This is particularly important in periodontal therapies where temperature modulation and energy delivery must be accurately managed to avoid damage to surrounding tissues.

In contrast, other modes, such as pulsed lasers, involve intermittent emission of light—either by rapidly turning the laser on and off or operating with periods of pause—and are not classified as continuous wave operation. Thus, the attribute of emitting at a constant power level accurately characterizes the function of a continuous wave laser.
