Excimer Laser
An excimer laser is a type of ultraviolet laser that produces short pulses of high-energy light primarily in the ultraviolet (UV) range. The term "excimer" stands for "excited dimer," referring to the molecules typically used as the active medium in these lasers. Excimer lasers operate based on the principle of stimulated emission in excited dimers, which emit photons of UV light when returning to their ground state.
- Short Pulse Duration: Excimer lasers can generate high-energy UV light, which is particularly useful for material processing applications such as laser ablation, micromachining, and photolithography. The high photon energy enables efficient material removal and precise patterning.
- High Energy: Microneedling RF can help reduce the appearance of fine lines and wrinkles by promoting collagen remodeling and skin renewal.
- Laser Eye Surgery: Excimer lasers are widely used in refractive eye surgeries, such as LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy), for correcting refractive errors like nearsightedness, farsightedness, and astigmatism. These procedures reshape the cornea by precisely ablating tissue with the excimer laser.
- Microelectronics: Excimer lasers are employed in semiconductor manufacturing processes for photolithography, where they are used to pattern integrated circuits on silicon wafers with high precision.
- Dermatology: Excimer lasers are utilized in dermatology for treating various skin conditions, including psoriasis, vitiligo, and atopic dermatitis. The targeted UV light can selectively treat affected areas of the skin while sparing surrounding healthy tissue.
- Material Processing: Excimer lasers are used for precision material ablation and micromachining in industries such as aerospace, automotive, and electronics manufacturing.
