RUGBY, England , April 30, 2012 /PRNewswire/ -- JK Lasers, a subsidiary of GSI Group Inc. and a leading supplier of fiber lasers, Nd:YAG lasers, Q-Switched lasers, gas lasers, and associated process tools, announced today the launch of a two kilowatt (kW) fiber laser. (Logo: http://photos.prnewswire.com/prnh/20120305/NE64445LOGO) The new JK2000FL offers excellent beam quality and high processing powers, presenting manufacturers with a viable and cost-effective alternative to traditional laser sources. The JK2000FL can be used with different diameter processing fibers from 100 microns to 300 microns for cutting and welding sheet metal. The JK2000FL can cut up to 15mm thick low carbon steel (LCS), 6mm aluminum alloys and 10mm stainless steel (304SS). It can also weld up to 8mm LCS and 304SS. The JK2000FL delivers a stable output power from switch on, a consistent focused spot size and beam profile over the complete power range. It is also fitted with JK Lasers' detachable 'plug in, pre-aligned' (PIPA) beam delivery fibers, which incorporates patented back reflection protection to protect the laser from damage when processing highly reflective materials such as aluminum, copper, brass and titanium. Compared to Nd:YAG lasers, the JK2000FL is up to ten times more energy efficient, offering manufacturers substantial savings in terms of operational costs. Further savings are realized through the use of laser diode pumping at high conversion rates, delivering wall-plug efficiencies of over 25%. With a mean time to failure (MTTF) of over 300,000 hours, the diode laser pump source used in the JK2000FL enables extended system lifetimes. The JK2000FL retains key benefits from JK Lasers' successful lower power models, including excellent beam quality, user-friendly software, fast modulation and pulse shaping. It can be fitted with JK Lasers' modular range of bespoke process tools for optimal performance and can incorporate an optional timeshare unit that can simultaneously connect up to four separate workstations. With a compact footprint, the JK2000FL can be easily integrated into most production environments.
