What characterizes a gated pulse mode laser?

A gated pulse mode laser is characterized by its ability to emit light in periodic bursts, which are controlled by a shutter mechanism. This operation allows the laser to deliver energy in a way that minimizes thermal effects and optimizes its interaction with biological tissues. The controlled bursts are typically designed to coincide with specific phases of treatment, thus enhancing the effectiveness of the laser while potentially reducing the risk of damage to surrounding tissues.

In contrast, other modes have different operational characteristics: a continuously operating laser emits a constant beam without interruption, which can lead to excessive heat generation. Meanwhile, lasers that function in short, uninterrupted bursts do not utilize the gating mechanism, leading to a different impact on tissue and treatment outcomes. A laser that maintains a constant power level lacks the versatility and control that gated pulse lasers provide, making the gated pulse mode particularly useful in various periodontal applications.
