GKNQL series Infrared Lasers

Contact us

GKNQL series semiconductor solid-state infrared lasers include three types according to different average output power. By an end-pumped laser technology in design, this series of lasers have the advantages of high power, high beam quality and high reliability in laser output.



  • Laser resistor trimming

  • Bitmap marking

  • Materials processing

  • Scientific researching

  • Spray-painted materials, metal products and sapphire screens surface marking




  • Easy operation, stable performance and long service life;

  • Strong environmenal suitabiliy with a hermetically sealed design of the laser shell;

  • Convenient in controlling with three modes: internal control, external control and RS232 control.
