What is the main advantage of using a continuous wave laser?

The main advantage of using a continuous wave laser lies in its ability to provide a constant beam of light. This characteristic makes it particularly suitable for various procedures that require consistent energy delivery. In scenarios such as cutting or ablating tissue, the stable output allows for precise control over the amount of energy applied, ensuring that the treatment is both effective and safe.

In contrast, while options discussing pulsed effects, cost relative to other laser types, and similar effects to LED lights may have their own discussions and contexts, they do not accurately represent the principal benefit of continuous wave lasers. The uninterrupted energy from these lasers is crucial for applications like surgical procedures, where a steady mode of operation is necessary to achieve desired outcomes.
