What is Nd:YAG laser used for?

Published in Laser Applications 2 mins read

The Nd:YAG laser is primarily used for tissue heating, coagulation, and tumor treatment.

Nd:YAG Laser Applications

Nd:YAG lasers are powerful tools with diverse applications, particularly in medicine. Their ability to deeply penetrate tissue makes them ideal for various therapeutic procedures. Here’s a breakdown:

Medical Treatments

  • Tissue Heating: The laser's energy can be used to selectively heat tissue. This is useful for a variety of applications.

  • Coagulation: Nd:YAG lasers can coagulate blood vessels, helping to control bleeding during surgery or treat vascular lesions.

  • Tumor Treatment: These lasers are employed to treat tumors by heating and destroying cancerous tissue. The deep penetration allows for treatment of tumors located beneath the skin surface.

    • Power Range: These applications often require power levels in the tens of watts. Many Nd:YAG lasers are designed to operate within this range to achieve optimal results.

How Nd:YAG Lasers Work in Treatment

  1. The laser emits a specific wavelength of light that penetrates tissue.
  2. This light energy is absorbed by the tissue, causing it to heat up.
  3. The heat can be used to achieve different therapeutic effects:
    • Coagulation: The heat causes proteins to denature, leading to clotting of blood and closure of blood vessels.
    • Tissue Destruction: In tumor treatment, the heat leads to the destruction of cancer cells.


Application Function
Tissue Heating Raises tissue temperature for therapeutic effect
Coagulation Clots blood vessels to stop bleeding
Tumor Treatment Destroys cancerous tissue
