Fiber laser sources from 100 W single-mode lab-grade up to 30 kW industrial OEM — wavelength, pulse, power and beam-quality figures measured at the physicist's bench before the serial leaves Santa Clara.
Every source that ships from Santa Clara, Gilching or Tampere passes through six measurement gates — enforced by physicist-grade diagnostics, not marketing claims. Below is what each gate actually measures.
Coherent integrates legacy programs — original ultrafast, ROFIN industrial CO2/fiber, DILAS diode, Lumera picosecond, Lambda Physik excimer and II-VI optics — into a single platform. Integrators pick the photon, not the brand acronym.
HighLight DF / FL-ARM / FAP fiber platforms span single-mode 100 W laboratory sources through 30 kW industrial OEM modules. Each power class documents beam-quality, spectral width and power-stability envelopes at characteristic operating points.
Beyond 1064 nm fiber — UV DPSS, green 532 nm, picosecond / femtosecond ultrafast, CO2 slab and excimer 193 / 248 / 308 nm. Application engineers match the photon-material absorption curve before picking a platform.
Applications labs in Santa Clara (CA), Gilching (DE) and Tampere (FI) run first-article photon-material interaction studies — weld porosity, micromachining HAZ, foil joining and PV scribing — with PhD-level beam diagnostics.
Spectral beam combining and coherent beam combining push brightness beyond single-fiber limits. A research-grade capability now productized for directed-energy R&D, cutting-edge welding integration and battery-cell manufacturing lines.
Every industrial fiber source undergoes 24 – 72 hour burn-in at full-rated power with documented drift, pointing stability and thermal-lens figures. Customers receive a serial-specific birth certificate alongside the shipment.
Select an OEM-ready platform by wavelength, pulse regime and power class. Each card opens a characterization dossier request scoped to that specific platform.
