nLight HP Fibre Alta

The nLIGHT® alta™ is the first in a line of next generation medium and high power Continuous Wave (CW) fibre lasers, ranging from 3000 Watts for thin material processing, up to 8000 Watts for thick material cutting and welding. This generation of lasers are designed to exceed user expectations, both in terms of performance and reliability, a must for OEM and bespoke machine builders manufacturing for industrial applications.

nLIGHT® alta™ incorporates several improvements over other commercially available fibre lasers, these include:

  • Advanced cutting and welding performance
  • Fail safe processing of highly reflective materials
  • Proprietary design, for high up time and ease of service
  • Designed for durability and to operate in harsh environmental conditions
  • Laser powers from 3000W up to 8000W
  • QBH Connector as standard.
  • Optional fibre-to-fibre coupler or beam switch available
  • Fibre core sizes from 50µm to 300µm
  • Fibre delivery lengths of up to 30 meters

The nLIGHT® alta™ range of lasers are typically used for industrial welding, Industrial cutting and thin metal processing applications. Coupled with nLIGHT’s back reflection isolation technology you can operate these lasers continually at full power, processing highly reflective materials with a comprehensive selection of processing heads and application specific accessories.

The nLIGHT® alta™ range of lasers are capable of delivering modulation rates of up to 100 kHz and rise and fall times of less than 5 µs, with anti-back reflection isolation included.  This technology allows uninterrupted full power processing of highly reflective materials, achieving faster processing of fine features.

nLIGHT® alta lasers incorporate a unique, proprietary fiber laser architecture that enables OEM, bespoke system builders and end users to manage common field service events, this results in higher machine uptime, lower cost of ownership, and an improved customer experience
