Ytterbium-doped fiber lasers operating at 1 um in CW and pulsed modes — up to 2000 W output power, air-cooled, with M² < 1.5. Engineered for marking, cutting, engraving, and precision welding.
Industrial-grade continuous wave fiber lasers operating at 1080 nm, designed for cutting, welding, cladding, cleaning, and advanced manufacturing. Featuring excellent beam quality, high electro-optical efficiency, and reliable 24/7 operation.
The FL-P series provides high peak power in nanosecond pulses — ideal for fine marking, deep engraving, and cutting where thermal effects must be minimised.
Complete parameter comparison across all FL-series models. All values measured at nominal operating conditions: 25 °C ambient, rated input voltage, after 30-minute thermal stabilisation. CW models require an external water chiller (not supplied). Specifications are guaranteed min/max unless marked typical (typ.).
