EV Battery Manufacturing

FL-ARM ring-mode fiber has become the integrator-preferred tool for copper-foil tab welding, aluminum busbar joining and hairpin winding in EV battery cell lines. The core / ring power split stabilizes the keyhole-to-conduction transition that historically blocked reliable 200 µm Cu welding.

Representative platforms: FL-ARM 3 – 12 kW ring-mode fiber, HighLight DF 1 – 6 kW single-mode
Typical process ranges: 100 – 400 µm Cu, 200 µm – 1 mm Al, 150 – 250 mm/s seam speed
Quality framework: spatter mass limits, HAZ audit, cross-section porosity scoring per OEM PPAP protocol

Semiconductor & Lithography

Lambda Physik excimer (193 / 248 nm) anchors photolithography, wafer annealing and LCD recrystallization processes worldwide. Coherent's long-gas-lifetime chamber engineering extends pulse-count envelopes that directly drive fab cost-of-ownership models.

Representative platforms: Lambda Physik 193 / 248 / 308 nm excimer, Verdi 532 nm DPSS, Obis UV
Typical process ranges: 600 – 1200 W avg excimer power; MHz repetition rate UV DPSS
Quality framework: pulse-energy stability, spectral bandwidth, pointing stability, photon-dose traceability

Medical Device Micromachining

Monaco femtosecond is the Tier-1 choice for cardiovascular stent cutting, bio-absorbable polymer device fabrication and ophthalmic surgical applicator assembly. 250 fs pulses produce essentially recast-free edges on cobalt-chromium and magnesium alloys — critical for FDA biocompatibility filings.

Representative platforms: Monaco 1035 nm femtosecond, HyperRapid NX picosecond, Verdi scientific
Typical process ranges: 80 – 400 µm tubing, 250 fs – 2 ps pulse regime, μJ-scale pulse energies
Quality framework: HAZ < 2 µm, crack-free metallography, edge-roughness profile, FDA 510(k) device-process documentation

Aerospace Hole Drilling

Turbine blade cooling holes, film cooling channels and igniter spray nozzles rely on pulsed fiber and ultrafast drilling — where sub-micron edge quality and minimized recast are the gating constraints. HighLight DF and Monaco femtosecond are both qualified into NA and EU turbine programs.

Representative platforms: HighLight DF pulsed fiber, Monaco femtosecond, HyperRapid NX picosecond
Typical process ranges: 200 – 800 µm hole diameter, Inconel 718, single-crystal superalloys, thermal-barrier coatings
Quality framework: recast < 2 µm, crack-free edges, AS9100-aligned process-audit documentation

PV / Solar Cell Scribing

Thin-film PV scribing, emitter wrap-through and selective-emitter patterning drive demand for high-repetition pulsed fiber and picosecond sources with tight pulse-to-pulse energy stability. Coherent pulsed platforms are deployed across multiple gigawatt-scale thin-film lines.

Representative platforms: HighLight DF pulsed, HyperRapid NX picosecond, Avia nanosecond UV
Typical process ranges: 15 ps – 30 ns pulse regimes, 50 kHz – 1 MHz repetition, 355 / 532 / 1064 nm
Quality framework: scribe width uniformity, shunt-free edge verification, module-level efficiency audit

Scientific Research & Quantum

Verdi CW green, Chameleon Ti:Sapphire and Monaco ultrafast anchor the world's biophotonics, attosecond-physics, nonlinear-optics and emerging quantum-computing experimental systems. Coherent sources appear in many of the laboratories awarded the Nobel Prize in Physics for laser-related programs.

Representative platforms: Verdi V-18 CW 532, Chameleon Ultra II Ti:Sapphire, Monaco ultrafast
Typical process ranges: CW milliwatt – 18 W; ultrafast 140 fs – 10 ps; tunable 680 – 1080 nm
