JK Series CW Lasers with SuperModulation Models
The JK401, JK501, JK802, JK1002 Lasers
We now offer something better than just CW. Our customers have gained higher performance welding and cutting, with high reliability and low process cost. The JK Series lasers are available with a combination of time and energy share modules. Up to six time shares and six-way energy shares are available. In addition, the lasers are offered with our patented Luminator™ fiber-optic beam delivery system. These plug-in pre-aligned (PIPA) fiber optics make allowance for rapid set-up and changeou–without the need for service intervention–and have been devised for long life in uninterruipted robotic or multi-axis applications. Consider these benefits:
- Next-generation designed for increased reliability and reduced cost of ownership
- Unique SuperModulation™ widens process window and increases capability
- Products range from 400—1000W average power at the workpiece with 800—2000W maximum modulated peak power
- Patented Luminator™ pre-aligned fiber-optic beam delivery system prevents back reflection damage to the fiber
- Graphical user interface software decreases level of experience required to operate the system
- Remote diagnostic access for increased support efficiency
GSI Lumonics’ JK Series of continuous wave (CW) Nd:YAG lasers is a product family ranging from 400 to 2000 Watts. Used for fast keyhole welding, efficient metal and silicon cutting, heat treating, and cladding, these lasers have demonstrated unmatched performance. These recognized performers also feature SuperModulation™, an innovative modulation technique that provides improved beam-material interaction for proficient and effective processing–giving them an edge over standard CWlasers.
Having introduced CWlasers in 1992, GSI Lumonics has now designed the third generation of product. GSI is committed to reducing total life cycle laser costs through innovation. These robust laser systems are the tangible result of thousands of hours of operating experience logged by GSI’s team of dedicated process engineers and application managers.
SuperModulation
Better than just CW, SuperModulation™ is a patent-pending technique in which some energy is stored in the laser’s power supply during the laser’s off-time or during a low average power cycle, and then is delivered to the lasing medium during a later time or during a high average power cycle. This produces a momentary output power that is up to 2X higher than that of the laser’s mean power rating for:
- More precise, higher penetration welding with less heat distortion and without compromising speed
- Cleaner, more controlled cutting of complex shapes
- Greater depth of focus
- Significantly improved processing of reflective materials
SuperModulation™ offers the speed of CWlaser processing with the control of a pulsed laser. Process engineers can control such factors as: weld penetration, heat effected zones, cooling rates, kerf quality, cornering speeds, and burnback; thus, users gain more control, improving performance, and getting optimal efficiency from their laser processing system.
