JK125P, JK300P  & JK300HP

A New Generation of JK Pulsed Nd:YAG Lasers

Another innovative member of the JK family of pulsed Nd:YAG lasers is available.  The JK125P, JK300P  & JK300HP models combine higher peak powers with shorter pulse lengths for increased robustness, providing the utmost in flexibility and maximized process control for quicker yet more precise welding and fine cutting applications.

  • Most compact footprint in class • Faster control interfaces and complete cycle programming triggered by a single command through our unique LaserView™ control technology
  • Class-leading reliability and built-in back reflection protection with our patented Luminator™ plug-and-play fiber optic delivery system
  • Tighter process control and reduced costs with our “pulse shaping” feature via our patented switch-mode power supply
  • Fully integrated time- and energy-share options

Proven production with important new field-tested enhancements

Considered a benchmark in the industry, the award-winning JK700 series of Nd:YAG lasers has been used to measure pulsed Nd:YAG laser performance.  In our new generation JK-HP and P Series lasers, GSI Group has combined over three decades experience in industrial laser manufacturing exploiting enhanced technologies for the best overall value, dependability, and cost of ownership for users of pulsed lasers.

Spanning a range of power levels, the JK-HP and P Series marks the introduction of a number of valuable features as standard across the JK product line, enhancing performance and process efficiencies while reducing integration and operating costs, training, and parts holding requirements for all users. Backed by GSI Group’s industry-leading applications expertise and worldwide support network, these reliable lasers will work harder than ever for you. Unique features our customers will enjoy include:

  • LaserView™ control technology, enabling complete cycle programming triggered by a single command
  • Patented Luminator™ fiber optic beam delivery with backreflection protection
  • Pulse shaping capability for tighter process control
  • Faster shutter interface for quicker response on parameter changes
  • More precise timing in time-share mode
  • Fully integrated time and energy shares for faster switching and reduced upkeep expenses
