10600nm CO2 Laser Aesthetic Diffractive Beamsplitter 9×9 Spot Array Description

10600nm (10.6μm) is the typical wavelength for infrared lasers emitting carbon dioxide. Laser energy at this wavelength is strongly absorbed by water molecules, making CO₂ lasers primarily used in medical aesthetics for fractional laser resurfacing and skin reconstruction applications.

The 10600nm CO2 Laser Aesthetic Diffractive Beamsplitter is a core optical component in CO2 laser treatment devices. By creating nanoscale microstructures on the surfaces of silicon and germanium materials, we can modify the wavefront. When a high-energy 10600nm CO2 laser beam strikes the diffractive beamsplitter, it converts the single laser beam into a 9×9 array of highly coherent laser dots. Each dot possesses extremely high laser energy density, enabling precise skin treatment.

10600nm CO2 Laser Aesthetic Diffractive Beamsplitter 9×9 Spot Array Product Features:

• Specifically optimized for 10.6μm CO₂ lasers.
• Diffraction efficiency exceeds 70%, with over 70% of incident laser energy distributed to fewer than 81 focal points, minimizing stray light.
• Available in germanium or zinc sulfide materials, both exhibiting high absorption at 10.6 microns with superior optical properties.
• High laser damage threshold enables the beam splitter to withstand CO₂’s high laser energy density without degradation.
• Exceptional beam splitting uniformity, with a maximum to minimum spot energy difference of less than 4.5%.

10600nm CO2 Laser Aesthetic Diffractive Beamsplitter 9×9 Spot Array Application

• Acne Scar Repair
  Traditional large-area laser resurfacing for acne scars involves a lengthy recovery period and significant risks. The 10600nm laser diffracted through a 9×9 beam splitter creates thousands of microscopic pores within the scarred area. Each laser beam vaporizes a tiny fragment of scar tissue, improving scar smoothness and skin texture.
• Surgical and Traumatic Scars
  Hypertrophic scars resulting from surgery are hard, well-vascularized, and may cause itching. High-energy CO₂ lasers effectively vaporize and level elevated scar tissue. Through precise thermal action, they remodel disorganized collagen fibers within the scar and seal excess capillaries, thereby improving scar thickness, hardness, and color.
• Removal of Benign Skin Lesions
  Lesions such as syringomas and sebaceous hyperplasia require precise and complete removal. The 9*9 beam splitter delivers extremely high energy density, capable of instantly vaporizing these proliferative tissues. This approach offers non-invasive or minimally invasive removal of cosmetically concerning skin issues, featuring rapid procedure times, minimal bleeding, and quick recovery—balancing therapeutic efficacy with aesthetic outcomes.
