The Quasi-Continuous Fiber Laser Series ranges from 75W to 600W, with higher electro-optical conversion efficiency, better optical quality and lower maintenance cost.

1940nm QCW Fiber Lasers

Small, air-cooled form factor with QCW power up to 650W.

Our 1940nm series Continuous Wave (CW) and Quasi-Continuous Wave (QCW) fiber lasers deliver CW power up to 100 W and QCW pulsed power up to 625 W from a compact, air cooled, 48 V DC powered package. These highly reliable and energy efficient lasers operate at 1940nm wavelength and provides up to 7J of energy for your most demanding applications. Options include a high-power multi-mode output or a medium power single mode output, ideal for a diverse set of medical, industrial, scientific, aerospace and defense applications.

Features:

• 60W to 100W CW models provide power level and pulse energy options to support a range of applications.

• Customizable interface location and fiber length for ease of system integration.

• 625W of peak power & pulse widths as short as 50 us

• Equipped with air cooled package, eliminating need for a water chiller

STR Series High Power QCW Fiber Lasers

The Quasi-Continuous Fiber Laser Series ranges from 75W to 600W, with higher electro-optical conversion efficiency, better optical quality and lower maintenance cost. This series product is a perfect alternative of existing light-pumped YAG laser and is an ideal choice for spot welding, seam welding, boring and other industrial applications needing wide pulse and high peak due to its persified compatibility and the convenience for most YAG systems to use it with simple transformation.

Features:

  • High electro-optical conversion efficiency> 30%
  • Two work modes: continuous and pulse
  • Extremely stable output performance
  • Excellent light beam quality
  • Optional QCS / QBH output connector and output length
