Nd:YAG lasers are primarily used for laser-induced thermotherapy and surgical procedures.
Nd:YAG Laser Applications: A Detailed Look
The Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) laser, emitting light at 1064 nm, is a versatile tool with numerous applications. Its primary use centers around its ability to generate heat, which is utilized for both therapeutic and surgical purposes. Here's a breakdown of its uses:
Laser-Induced Thermotherapy
- Ablation of Lesions: Nd:YAG lasers are predominantly employed in laser-induced thermotherapy. This involves using the laser beam to heat and ablate (destroy) benign or malignant lesions. This technique is applied across various organs.
- How it Works: The laser's energy is absorbed by the tissue, causing a rise in temperature that leads to cell death in the targeted area. This controlled heating allows for precise treatment with minimal damage to surrounding healthy tissue.
Oncology Applications
- Skin Cancer Removal: In oncology, Nd:YAG lasers are used to remove skin cancers. The laser energy can precisely target and destroy cancerous cells.
Other Applications:
While the primary use falls under thermotherapy and oncology, Nd:YAG lasers have other applications:
- Cosmetic Procedures: They are used for hair removal, tattoo removal, and the treatment of vascular lesions (e.g., spider veins).
- Ophthalmology: Nd:YAG lasers are used in certain eye procedures, such as posterior capsulotomy, to improve vision after cataract surgery.
- Industrial Applications: The high power of Nd:YAG lasers makes them useful in material processing, such as cutting, welding, and marking.
Benefits of Nd:YAG Lasers
- Precision: The laser can be focused on specific areas, reducing the risk of damage to surrounding tissue.
- Versatility: It is used across various medical specialities, as well as non-medical fields.
- Effectiveness: Proven to effectively treat various medical conditions.
