RUGBY, England, July 19, 2010 — The JK Lasers division of GSI Group has announced the release of two additions to its JK range of pulsed Nd:YAG lasers. The JK80PS and JK150PS are designed for industrial processing, medical applications, electronics and automotive components. They combine higher peak powers with improved beam quality for increased flexibility and maximized process control for faster, more precise welding and fine cutting applications. Fiber sizes down to 100 µm and peak powers up to 5 kW enable peak power densities at smaller feature sizes than previously possible. The JK80PS delivers peak powers of up to 3 kW via a 100-µm fiber, and the JK150PS delivers 5 kW via a 150-µm fiber. All fibers are equipped with patented and proprietary Luminator Plug-In Pre-Aligned technology with integral backreflection protection and a built-in fiber continuity monitoring system for enhanced safety. Both lasers offer high pulse-to-pulse stability down to ±0.5% and include features such as pulse-on-demand and the company’s LaserView software suite. They also can be used with scanner-based delivery systems because the scanner-control software is designed for welding and cutting applications. Additional features include pulse shaping for tighter process control, a faster shutter interface for quicker response on parameter changes and more precise timing in time-share mode, and fully integrated time and energy shares for faster switching and reduced maintenance costs. The JK80PS delivers maximum average power of 80 W and maximum pulse energy of 17 J. The JK150PS delivers maximum average power of 150 W and maximum pulse energy of 35 J. For both, ambient temperature is from 5 to 40 °C, pulse width range is from 0.2 to 20 ms, and shutter opening time is <50 ms.
