Custom Er:YAG Crystal Rods & Slabs For 2940nm Medical Laser

Er:YAG Laser Crystals Rods and Slabs Product Discription

Er:YAG crystals are also known as Erbium YAG laser crystals. Asin Optics is a professional laser crystal manufacturer; we independently research, develop, and produce high-quality Er:YAG crystals. We are capable of customizing Er:YAG crystal components with large dimensions, high doping concentrations, and excellent optical homogeneity. Er:YAG is primarily used in the 2940 nm wavelength band and plays an irreplaceable, central role in soft tissue cutting, hard tissue ablation, dental treatments, urological lithotripsy, and aesthetic medical devices.
From crystal growth and processing to optical coating, we ensure that every Er:YAG crystal rod or wafer can withstand high laser damage thresholds and deliver stable laser performance.

Er:YAG Laser crystal Product Features

• The 2.94 μm output of Er:YAG laser crystals matches the main absorption peaks of water molecules and hydroxyapatite in the human body, enabling high ablation rates and minimal thermal damage in medical applications. It is primarily used for minimally invasive laser surgery.
• We can provide high-quality crystals for medical systems with Er³⁺ doping concentrations of 50% or less, thereby improving the high-slope efficiency of the pumping system.
• Using optimized annealing processes and controlled stress distribution, we produce crystals with low wavefront distortion and ensure excellent beam quality.
• We support customization of crystals in various shapes and sizes, including Er:YAG rods, strips, and wafers. Dimensions, crystal orientation, and end-face coating can be fully customized. We also offer services for composite crystals, such as bonding and diffusion.

Er:YAG Crystal Rods & Slabs Applications

• Dental Treatment

  The water and hydroxyapatite in teeth, as well as the moisture in the mucosa and gums, exhibit extremely strong absorption at a wavelength of 2940 nm, enabling instant vaporization of the target tissue. The Er:YAG dental laser crystal generates 2940 nm pulsed laser light, which is delivered into the oral cavity via an optical fiber or an articulated arm, allowing for highly efficient cutting of both soft and hard tissues.

• Aesthetic Skin Treatments

  The superficial epidermal layer of the skin contains a high water content. The laser emitted by the 2940 nm laser crystal precisely targets the peak absorption wavelength of water, with a penetration depth of only about 10–20 micrometers, allowing for precise, layer-by-layer ablation without carbonization. The 2940 nm laser crystal divides the laser into an extremely fine dot matrix of microbeams to remove aged keratin and smooth out acne scars.

• Other Medical Applications

  Bone, cartilage, and urinary tract stones also contain bound water and structural water, which are highly sensitive to the 2940 nm wavelength. Laser systems featuring the 2940 nm laser crystal as their core can be used for non-contact vaporization in otolaryngology, urology, and maxillofacial surgery.
