We carry Coherent products across the full industrial portfolio, from ExactMark marking systems and ExactWeld welding machines through StarCut Tube CNC cutting systems, HighLight fiber and diode lasers, and legacy Rofin-Sinar industrial laser platforms.

Coherent traces its origins to 1966, when James Hobart founded the original Coherent, Inc. in Palo Alto, California, as one of the earliest commercial laser enterprises. The company delivered the first industrial CO2 laser for materials processing, opening the market for laser-based metal cutting and welding. Coherent acquired Rofin-Sinar Technologies in 2016, consolidating high-power fiber laser and ultrafast laser capabilities into one of the broadest industrial laser portfolios globally. In July 2022, II-VI Incorporated completed its acquisition of Coherent, Inc., and the combined company was renamed Coherent Corp. (NYSE: COHR), headquartered in Saxonburg, Pennsylvania. Coherent Corp. now operates fabrication facilities across four continents in more than 20 countries, with over 2,590 employees worldwide. All facilities maintain AS9100D and ISO 9001:2015 certifications. As a vertically integrated photonics company, Coherent controls the entire value chain from semiconductor materials through laser sources, precision optics, and complete industrial systems.

The ExactWeld series (ExactWeld 230, 430) delivers turnkey laser welding of metal parts with fiber laser sources, multi-axis motion, and optional vision systems. The Select Manual Welder provides freestanding spot and seam welding. For cutting, the ExactCut micromachining system handles metals, alloys, and ceramics with pulsed fiber lasers. The StarCut Tube system offers up to 4-axis CNC laser tube cutting for medical stents, endoscope components, and precision tubular parts.

Coherent Laser Sources & Beam Delivery

Coherent manufactures a complete range of laser sources: HighLight FL fiber lasers (including ARM adjustable ring mode for EV battery welding), HighLight DL diode lasers for cladding and heat treating, PowerLine series markers, HyperRapid NXT ultrafast picosecond lasers, CO2 lasers, and excimer lasers. BIMO-FSC3 beam delivery heads handle up to 30 kW for high-power cutting and welding integration.

What to Look for When Buying Used Coherent Equipment

Coherent laser systems combine precision optics, high-power laser sources, multi-axis motion platforms, and integrated software into turnkey industrial machines. Used Coherent equipment can deliver significant value, but laser sources degrade over time and optical components require careful evaluation. Here is what to inspect on used units.

Test the laser source output and stability. Measure actual laser output power against the rated specification using a calibrated power meter. Fiber lasers, diode lasers, and CO2 lasers all degrade over operating hours. Compare measured output to the system's hour meter reading. On ultrafast (picosecond/femtosecond) sources, verify pulse quality and repetition rate stability. A laser source operating significantly below rated power may need diode replacement or refurbishment.

Inspect the beam delivery optics. Check all lenses, mirrors, and protective windows for contamination, coating damage, pitting, or thermal discoloration. On fiber-delivered systems (HighLight FL, ExactWeld), inspect the fiber connector end face and delivery cable for damage. On galvanometer-based scanning systems (ExactMark, PowerLine), verify that the scan mirrors produce accurate, repeatable positioning across the full marking field.

Test the motion system and CNC axes. On multi-axis systems (ExactWeld, ExactCut, StarCut Tube), verify smooth, accurate motion on all axes. Check for backlash, positioning accuracy, and repeatability by running a test program. On StarCut Tube 4-axis systems, test rotary axis function and synchronization with linear axes for accurate tube cutting.

Verify software licensing and control system. Coherent systems use Laser FrameWork software for marking and processing control. Confirm that software licenses transfer with the equipment and that the installed version supports your intended applications. Test all software functions including job setup, vision system integration (if equipped), and machine communication.

Coherent ExactMark Laser Marking Systems

The ExactMark 210 provides versatile laser marking with motorized Z-axis and optional tray loading (210 TL) for high-throughput automated processing. The ExactMark 230 USP combines ultrashort pulse laser technology with multi-axis motion for corrosion-resistant black marking on stainless steel, titanium, and aluminum, as well as marking on polymers including PEEK and PPSU. SmartMap3D enables 3D part recognition for marking on curved and irregular surfaces. ExactMark systems are the most commonly traded Coherent machines on the used market.

Coherent ExactWeld & Welding Systems

The ExactWeld 230 is a turnkey system for precision laser welding of small to medium metal parts, with a 200 W fiber laser (400 W optional), up to four CNC axes, and optional vision. The ExactWeld 430 brings higher-power fiber laser welding for production volumes. The Select Manual Welder is a freestanding system for spot and seam welds. Coherent's CleanWeld technology reduces spatter by up to 80% and allows certain processes to run with 40% less laser power.

Coherent ExactCut & StarCut Tube

The ExactCut micromachining system cuts metals, alloys, and ceramics with pulsed fiber laser sources and ships with preprogrammed process parameters. The StarCut Tube is a CNC laser tube cutting system (up to 4 axes) for medical device manufacturing, producing stents, heart valve frames, endoscope components, hypotubes, and surgical instruments. Available with fiber or femtosecond laser sources for conventional or cold cutting of virtually any material.

Coherent HighLight Laser Sources

The HighLight FL fiber laser series includes the FL-ARM (Adjustable Ring Mode) with independent center and ring beam control for EV battery welding. The HighLight DL diode laser series (DL4000HPR) provides compact, rack-mount high-power for cladding, heat treating, and brazing. The PowerLine Rapid NX serves industrial marking applications. The HyperRapid NXT delivers 10 W at 266 nm for demanding UV micromachining. Legacy Rofin-Sinar fiber and CO2 lasers remain widely traded on the used market.
