Laser Marking on Stone: Clean and Durable Engraving for Memorials and Gravestones

Stone has long symbolized permanence: honoring lives, milestones, and legacies in memorials, gravestones, and architectural dedications. Today’s technological shift moves beyond traditional chiseling and sandblasting. Laser marking on stone has emerged as a powerful, precise, and flexible solution for engraving materials like limestone, marble, and granite.

Advanced Optowave’s Breakthrough: AONano™ Compact Series

At the forefront of this transformation is Advanced Optowave Corporation (AOC) with its newly released AONano™ Compact Series. This state-of-the-art 10W industrial UV nanosecond laser system is expertly engineered for clean, high-contrast engraving on organic and non-metallic materials—including delicate stone surfaces.

Why Choose Laser Marking for Stone?

Laser marking is a non-contact, digital process that creates permanent marks by locally heating the stone. This method offers:

• Carbonization or Light Ablation: Producing natural, true-to-life engraving textures.
• Color Contrast: Achieving crisp white or gray marks on marble and darkened, high-contrast engravings on granite.
• Subtle Micro fracturing: Enhancing texture for a refined finish.

The outcome is a durable, maintenance-free mark, weather-resistant and perfect for memorials, gravestones, plaques, and pet markers.

Introducing the AONano™ Compact Series: Where Power Meets Precision

The AONano™ Compact Series sets a new standard for stone engraving by combining high power with refined precision. Key features include:

• Crystal Indexing for Automatic Power Optimization:
  Ensures consistent power output for stable, high-quality engraving throughout long production runs.
• Intracavity Clean Air System:
  Maintains a dust-free optical path, crucial for preserving internal components and beam integrity in stone-processing environments.
• IP65 Industrial Housing:
  With sealed protection against dust and moisture, it is designed to thrive in harsh conditions—from monument workshops to field installations.
• High-Contrast Marking on Light Stones:
  The 355 nm UV wavelength produces clean, crisp marks on materials like marble and limestone without the excess charring often seen with CO₂ lasers.

UV Laser vs. CO₂ Laser: Key Advantages

While CO₂ lasers excel in deep engraving and creating rustic marking effects, UV nanosecond lasers offer several distinct advantages:

• Superior Edge Quality and Surface Finish:
  Achieve fine details without compromising quality.
• Minimal Thermal Damage:
  Reduces the risk of cracks or discoloration, preserving the integrity of the stone.
• Higher Resolution Capabilities:
  Ideal for photo engraving, intricate script, and precise symbols.

With the AONano™ Compact Series, users enjoy the best of both worlds—combining high power with a clean, high-resolution finish.

Common Applications for Laser-Marked Stone

Laser marking brings endless creative possibilities in memorial and architectural contexts. Applications include:

• Gravestones and Headstones:
  Engraving names, dates, scripture, and religious icons with clarity.
• Memorial Plaques:
  Featuring dedications, portraits, or historical inscriptions that stand the test of time.
• Architectural Markers:
  Including building cornerstones, donor walls, and public installations.
• Pet Memorials:
  Custom stone tributes that gracefully honor beloved pets.

Digital control in laser marking allows for precise layouts, real-time design customization, and repeatable output—enhancing both creative freedom and production efficiency.
