Laser Annealing Technology

Laser annealing is a specialized marking process that differs from traditional engraving methods. Instead of removing material, annealing heats stainless steel or titanium below its melting point, inducing a controlled oxidation process that creates a permanent, contrasting oxide layer. The result is a smooth and dark mark that is visible on the material surface.

While engraving removes metal from a surface, laser annealing alters its color from within. This process ensures that the surface remains intact and there is no opportunity for micro-grooves to form in which bacteria can collect. This characteristic is essential for FDA-regulated industries, like the medical sector, where device surfaces must withstand multiple sterilization cycles.

Why Use Our Laser Annealing Machines?

Our laser annealing machines are designed for seamless integration into automated production environments.

  • Mark-on-the-fly capabilities: Our systems support high-speed manufacturing by marking products as they move along a conveyor or assembly line. Mark medical tubing as it extrudes to maximize throughput.
  • Vision systems: To ensure mark quality and regulatory compliance, our integrated vision systems, powered by Merlin® software, verify the mark’s contrast, legibility and placement after annealing.
  • User-friendly enclosures: Telesis Technologies, Inc. provides ergonomic enclosures, such as the ProStation™, ensuring Class 1 laser safety during operation while facilitating efficient, high-volume part loading and unloading.

Laser Annealing Equipment Applications

Uses for laser annealing equipment in the industries we serve are outlined below.

Compliance with regulations like Unique Device Identification (UDI) is mandatory within the medical field. Laser annealing machines enable equipment operators to mark:

  • Surgical tools: Ensure UDI traceability on instruments that undergo autoclaving.
  • Implants: Mark implants without compromising biocompatibility or creating sites for bacterial adhesion.
  • Catheters: Prioritize sterilization to mitigate risks that could compromise patient safety.

The aerospace industry demands extreme precision and reliability. Laser annealing is useful for turbine blades and structural parts where deep engraving would create cracks that lead to premature failure. Laser annealing creates a surface-level mark that preserves material strength and maintains corrosion resistance.

Manufacturers choose laser annealing to preserve a metal’s passive oxide layer, preventing degradation. Aerospace components can be confidently exposed to harsh conditions without compromising their integrity.

MOPA Annealing Equipment

Master Oscillator Power Amplifier (MOPA) fiber laser technology serves as the foundation for your procedures. Telesis Technologies, Inc. offers the XpressMark MOPA™ Fiber Laser, recognized as the gold standard for laser annealing applications.

  • Pulse width control: Unlike standard fiber lasers, MOPA technology allows for precise control over the pulse duration (measured in nanoseconds). This fine-tuning capability enables manufacturers to heat the metal and create the desired oxide layer without material ablation or cutting.
  • Vanadate options: For reflective metals or heat-sensitive plastics that may not be compatible with fiber lasers, Telesis Technologies, Inc. offers vanadate lasers. These systems provide an alternative for specialized materials, expanding our range of laser annealing equipment solutions.
