Cutting, Welding & Surface Treatment

Coherent materials processing lasers cover the full spectrum from multi-kilowatt CW fiber lasers for 30mm+ mild steel cutting to nanosecond pulsed sources for fine marking on hardened tools. Our HighLight FL series delivers wall-plug efficiencies above 40%, which translates directly to lower cost-per-part on 24/7 production lines.

Welding applications benefit from adjustable beam profiles through our proprietary ARM (Adjustable Ring Mode) technology, enabling operators to independently control core and ring beam power for optimal keyhole stability in aluminum, copper, and dissimilar metal joints, a common challenge in EV battery module assembly.

  • Cutting: 1-30kW fiber lasers, carbon steel up to 40mm, stainless steel up to 30mm
  • Welding: ARM beam shaping, 2-12kW, copper and aluminum capable
  • Marking: 20-100W pulsed fiber and UV sources, cycle times under 2s per part
  • Surface treatment: Laser hardening, cladding, and cleaning up to 3kW

Coherent Optics for Data Center & Telecom

The exponential growth in data center traffic, driven by AI training workloads and cloud-scale infrastructure, demands optical links with higher baud rates, lower power consumption, and smaller form factors. Coherent pluggable optics address all three constraints simultaneously.

Our 400ZR/ZR+ and 800G coherent modules use proprietary InP-based transmitter and receiver photonic integrated circuits (PICs) co-packaged with Coherent DSP ASICs. This level of integration achieves power consumption below 15W per 400G module, roughly 60% lower than discrete implementations from three years ago.

  • 400G ZR/ZR+: QSFP-DD and OSFP form factors, 120km+ reach
  • 800G: Next-gen coherent modules for DCI and metro
  • Point-to-point: Full-duplex coherent optics for enterprise WAN
  • Test solutions: Coherent optical test instruments for deployment validation

Semiconductor Manufacturing

Laser Processes at the Leading Edge

Semiconductor manufacturing requires nanometer-scale repeatability across billions of features per wafer. Coherent excimer lasers have served as the photon source for DUV lithography scanners for over two decades. Our LineBeam systems for LTPS (low-temperature polysilicon) annealing deliver the beam uniformity needed for OLED display backplane crystallization.

Beyond lithography, our ultrafast sources enable laser dicing of thinned wafers without thermal damage to adjacent circuitry, a critical step in advanced 3D packaging where die thickness is below 50 micrometers. Measurement instrumentation from our legacy Rofin and II-VI portfolios provides in-line power monitoring at every process step.

  • Lithography: ArF and KrF excimer lasers for DUV exposure
  • Annealing: LineBeam systems for LTPS and ELA processes
  • Dicing/drilling: Ultrafast ps/fs lasers for damage-free singulation
  • Metrology: In-line power sensors and beam profilers

Ultrafast & Tunable Lasers for Discovery

The Coherent scientific laser portfolio, built on our Chameleon, Monaco, and Astrella platforms, serves researchers who need broadly tunable output, high pulse-to-pulse stability, and hands-off reliability over thousands of operating hours. Our Ti:Sapphire oscillators deliver sub-10 femtosecond pulses with less than 0.1% RMS intensity noise, a specification that directly impacts signal-to-noise in multiphoton fluorescence microscopy.

Importantly, we acknowledge that tunable Ti:Sapphire systems face competition from fiber-based OPA (optical parametric amplifier) architectures, particularly at repetition rates above 1 MHz. However, for applications below 100 kHz where peak power and broad wavelength tunability from 680-1080nm are essential, the Ti:Sapphire platform remains the gold standard validated by over 15,000 peer-reviewed publications citing Coherent sources.
