ClearShape industrial laser cutting process

  • Highest quality cutting of strengthened and unstrengthened glass and sapphire
  • High >1000 mm/s cutting speed
  • As-cut bending strength of up to >650 MPa

Spectra-Physics introduces ClearShape™, a patent-pending femtosecond laser process for highest quality, fast cutting of chemically strengthened glass, unstrengthened glass, and sapphire. At speeds over 1000 mm/sec, the new process results in several-fold improvement in cut quality over other laser processes: no chipping, Ra <0.1 µm edge roughness, and as-cut bending strength of >650 MPa for chemically strengthened glass. Utilizing the widely deployed Spirit® family of industrial femtosecond lasers, the new process is ideal for 24/7 manufacturing of displays and windows for mobile devices, wearables, and other demanding applications.
