What is Nd:YAG laser used for?

Nd:YAG Laser Applications

The Nd:YAG laser is a solid-state laser that employs a neodymium-doped yttrium aluminum garnet (Nd:YAG) as the lasing medium. The Nd:YAG laser operates at a wavelength of 1064 nm, which lies in the infrared region of the electromagnetic spectrum. Its unique properties make it suitable for a broad range of applications across various fields.

Medical Uses

• Ophthalmology: Used in posterior capsulotomy and peripheral iridotomy procedures. It is also employed for retinal photocoagulation in diabetic retinopathy, and for repairing retinal detachment.
• Dermatology: Removes skin lesions, unwanted hair, and tattoos. It also treats pigmented lesions and vascular lesions.
• Dentistry: Used for oral soft tissue surgery, enamel etching, and for detecting caries.
• Cancer Treatment: Applied in photodynamic therapy for cancer treatment using light-sensitive drugs activated by the laser.

Industrial Uses

• Material Processing: Employed for cutting, welding, drilling, and marking metals and non-metals.
• Additive Manufacturing: Utilized in selective laser sintering (SLS) processes for 3D printing.

Military and Scientific Uses

• Target Designation and Range Finding: Used as a part of laser designator systems for guiding precision-guided munitions.
• Research: Applied in spectroscopy, nonlinear optics, and as a pump source for other types of lasers.

In aesthetic medicine, the Nd:YAG laser is effective for skin rejuvenation, reducing the appearance of wrinkles, and treating spider veins.

In conclusion, the versatility and effectiveness of the Nd:YAG laser have made it an invaluable tool in various sectors, from healthcare and defense to manufacturing and research.
