2-kW Fiber Laser

RUGBY, England, May 2, 2012 — A 2-kW fiber laser launched by JK Lasers offers good beam quality and high processing powers. The JK2000FL presents manufacturers with a viable and cost-effective alternative to traditional CO2 and Nd:YAG lasers.

It can be used with processing fibers with diameters from 100 to 300 μm for cutting and welding sheet metal. It can cut 15-mm-thick low-carbon steel (LCS), 6-mm aluminum alloys and 10-mm stainless steel (304SS), and can weld 8-mm LCS and 304SS.

Automotive applications include tailored blank welding, component welding, remote welding and hydroformed tube cutting. In the aerospace industry, it can be used for titanium welding of aircraft skins and structures as well as laser cladding.

The JK2000FL delivers stable output power from switch-on, as well as a consistent focused spot size and beam profile over the power range. It is fitted with proprietary detachable plug-in prealigned beam delivery fibers that incorporate patented backreflection protection to shield the laser from damage when processing highly reflective materials such as aluminum, copper, brass and titanium.

The use of diode pumping at high conversion rates makes the laser more energy-efficient than Nd:YAG models and delivers wall-plug efficiencies of >25%. The >300,000-h mean time to failure for the individual laser pump sources enables extended system lifetimes.

Features include user-friendly software, fast modulation and pulse shaping. The laser can be fitted with the company’s modular range of process tools for optimal performance and can incorporate an optional time-share unit that simultaneously connects up to four separate workstations. With a compact footprint, it can be easily integrated into most production environments.
