Picosecond Laser Glass Cutting Machine: Applications, Compatible Glass Types, and Cutting Parameters

1. Core Application Industries

1.1 Consumer Electronics

• Target Materials:

  • Smartphone/tablet cover glass (e.g., Corning Gorilla Glass, AGC Dragontrail).

  • Curved glass for wearables (e.g., smartwatches, AR/VR lenses).

• Key Requirements:

  • Ultra-thin glass cutting (0.3-1.1 mm) with anti-cracking technology.

  • High-precision shaped cuts (e.g., camera holes, fingerprint modules) with ±5 μm accuracy.

• Case Study:

  • A global smartphone manufacturer uses a 20W picosecond laser to cut 0.7 mm microcrystalline glass, achieving edge chipping <10 μm.

1.2 Automotive & Autonomous Driving

• Target Materials:

  • Curved glass for automotive triple-screen displays (1.5-3 mm thickness).

  • Quartz optical windows for LiDAR systems.

  • HUD projection glass with anti-glare coatings.

• Technical Edge:

  • 3D dynamic focusing for cutting curved surfaces (radius ≥8 mm).

  • Heat-affected zone (HAZ) <30 μm, critical for optical clarity.

• Case Study:

  • Automotive uses a 30W system to cut LiDAR-grade fused silica lenses (1.2 mm thickness).

1.3 Advanced Display Manufacturing

• Mini/Micro LEDCutting 0.2 mm ultra-thin glass substrates (CTE <3.5×10/K) with 2 μm line accuracy.

• OLED Flexible Screens:

  • Delicate cutting of glass encapsulation layers (50-100 μm) on PI substrates, using pulse energy <10 μJ to prevent delamination.

1.4 Precision Optics

• High-End Applications:

  • Fluorophosphate optical glass (refractive index: 1.45-1.9) cutting for lenses and prisms.

  • 
    
    Infrared chalcogenide glass (e.g., Ge28Sb12Se60) for thermal imaging systems.

• Case Study:

  • UK-based Renishaw utilizes a 25W picosecond laser to cut 80 mm diameter sulfur-basd glass lenses at 300 mm/s.

2. Glass Types & Cutting Parameters Matrix

3. Power vs. Threshold Guidelines

• General Rule:

  • Power (W) ≈ 2 × Glass Thickness (mm) + 10 (for standard soda-lime glass).

  • Example: 2 mm glass → ~14W minimum power (add 20-50% buffer for complex shapes).

• Speed Adjustment:

  • For every 0.1 mm thickness increase, reduce speed by 15-20 mm/s (for borosilicate).

4. Industry-Specific Technical Highlights

• Medical Devices (US Market Focus):

  • Cutting 1 mm bioactive glass (e.g., 45S5 Bioglass®) for endoscopic tools with zero toxic byproducts.

• Aerospace (UK/Germany Focus):

  • 3 mm aluminosilicate glass cutting for aircraft cabin windows (Ra <0.4 μm post-cutting).

• Renewable Energy (US/Germany):

  • CdTe thin-film solar glass cutting using 20W + fume extraction to prevent Cd release.
