Spectra-Physics Unveils Novel Industrial Laser Glass Cutting Process


Unprecedented high bending strength and cut quality results from new high speed process

Santa Clara, CA - February 9, 2015 - Spectra-Physics®, a Newport Company, 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/s, 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.

"The new ClearShape process delivers remarkable results, far and away superior to that of other laser glass and sapphire cutting processes," says Klaus Madlener, general manager of Spectra-Physics Rankweil. "We are excited to see intense customer interest in the potential of this technology for volume manufacturing applications."

Spectra-Physics also introduces Spirit 1040-16, a high power addition to its Spirit family of industrial femtosecond lasers. The new laser delivers >16 W average output power with ultrashort <400 fs pulse width, 40 µJ pulse energy, and repetition rate up to 1 MHz. Spirit 1064-16 is ideal for fast, cold micromachining of semiconductors, flat panel displays, and other microelectronics manufacturing applications. Spirit is a thoroughly proven industrial platform and has passed extensive environmental qualification testing to ensure high reliability.

Spectra-Physics' ClearShape process and Spirit 1040-16 laser will be featured at SPIE Photonics West, Moscone Center, San Francisco, California, February 10-12, 2015. Please visit Spectra-Physics at booth #1401 for a demonstration. For more information, please see
