In medical industry, YAG lasers have found profound importance. They have emerged as a crucial tool in modern medical therapy devices, redefining treatment capabilities across multiple clinical specialties. Short for yttrium aluminum garnet (Y₃Al₅O₁₂), this laser medium is doped with neodymium (Nd:YAG). YAG lasers are capable of producing high-intensity light that can penetrate tissue with precision and controlled depth. As healthcare moves toward minimally invasive, highly targeted therapies, YAG lasers are playing a leading role. When used in therapeutic devices, they help to enhance safety, expand treatment options, and drive innovation in therapeutic devices.
YAG laser technology and its use in therapeutic devices
Therapeutic devices rely on Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) lasers, which can produce infrared light at specific wavelengths (like 1064 nm and 532 nm). This wavelength allows deep tissue penetration with relatively low absorption in water and hemoglobin, an important feature making Nd:YAG lasers especially suitable for medical use. The physical properties of YAG crystals, like high thermal conductivity, mechanical strength, and optical clarity, enable them to produce stable, reliable laser output for medical instruments.
With focused and monochromatic (single-wavelength) beam, practitioners can deliver energy precisely where it is needed without damaging surrounding tissues. This precision offers many therapeutic advantages.
Advantages of YAG lasers in therapeutic devices:
Precision and selectivity
One of the most important benefits of YAG laser therapy is its precision. The energy can be focused to very small spots, allowing surgeons and therapists to treat specific structures without affecting adjacent areas.
Deep tissue penetration
The infrared wavelength of Nd:YAG lasers enables them to penetrate deeper into tissues, making them suitable for therapies that require reaching deeper anatomical structures, like deep vascular lesions.
Minimally invasive approach
Because YAG lasers can remove or modify tissue without large incisions, it is suitable for minimally invasive procedures.
ERDI Tech Ltd helps to leverage YAG laser technology for use in ophthalmology, musculoskeletal conditions, dentistry, imaging, and others.
