Vivlaser (Shenzhen Vivlaser Technology Co., Ltd.) has officially launched a new 10kW–100kW semiconductor laser heating system designed for industrial applications that demand large-area coverage, high efficiency, and high thermal uniformity. The system supports mainstream 915nm and 976nm semiconductor wavelength options and delivers a variable square/rectangular beam ranging from a few square centimeters up to a full square meter. Through beam-shaping and homogenization design, the system achieves greater than 95% beam uniformity, providing a stable laser heating solution for metal preheating, composite material curing, surface treatment, coating preheating, and zone heating on automated production lines.
Building on its modular beam-combining and system integration capabilities, Vivlaser also offers higher-power, multi-ten-kilowatt-class laser heating solutions — including 40kW, 60kW, and higher configurations.
As smart manufacturing, high-end equipment production, new energy materials processing, and automated production lines continue to advance, industrial heating is shifting away from traditional hot air, resistance wire, hot plate, and infrared methods toward more precise, energy-efficient, and controllable semiconductor laser heating. For large workpieces and continuous production lines, heating speed, temperature consistency, energy consumption, and system integration have become key factors affecting both process quality and production cost.
The Limits of Traditional Heating Are Driving the Shift to Laser Heating
Conventional industrial heating methods — hot air, hot plates, resistance wire — rely mainly on conduction or convection to raise temperature. These approaches are structurally simple, but on large workpieces they often suffer from high thermal loss, slow heating, uneven temperature distribution, localized overheating, or insufficient edge temperature. For metal sheets, composite panels, rail transit components, and shipbuilding parts, these issues directly affect the quality of subsequent welding, bonding, coating, curing, or surface treatment.
Vivlaser's semiconductor laser heating system uses a non-contact method, applying laser energy directly to the target area and reducing unnecessary heat transfer steps. By combining a large beam footprint with a uniform thermal field, the system improves heating efficiency while keeping temperature control more stable — well suited to industrial processes that demand high consistency.
915nm / 976nm Semiconductor Wavelength Options: Balancing Efficiency and Process Fit
In industrial laser heating, wavelength choice affects material absorption efficiency, thermal response speed, and process window. Vivlaser offers 915nm or 976nm semiconductor wavelength configurations based on the customer's material properties and application needs.
The 915nm option is a mature, stable-output solution suited for metal preheating, composite material processing, and general industrial heat treatment. The 976nm option offers strong performance in material absorption and heat-conversion efficiency for certain materials, making it a good fit for processes that require faster thermal response and higher energy utilization. Choosing the right wavelength lets customers achieve better heating results across different materials, surface conditions, and production cycle times.
Square/Rectangular Beam Shapes Matched to Large Industrial Workpieces
Unlike the point or line beams used for cutting and welding, industrial heating is primarily concerned with thermal coverage area and temperature distribution. Vivlaser's semiconductor laser heating system outputs a square or rectangular beam that better matches the actual shape of sheets, plates, strips, and other regular-structure workpieces.
This area-beam design reduces the efficiency losses associated with multi-pass scanning, delivers more direct heat coverage, simplifies process tuning, and integrates more easily with robots, linear modules, roller conveyors, and PLC control systems. For customers running continuous, high-volume production, the square/rectangular beam is not just an optical design choice — it's a key factor in improving line throughput and heat-treatment consistency.
Homogenized Beam (>95% Uniformity) for Stable High-Power Heating
High power alone does not guarantee high quality. For industrial heating systems, beam uniformity is often the direct determinant of whether a workpiece's surface temperature stays stable. Through beam-shaping and homogenization technology, Vivlaser's system achieves greater than 95% beam uniformity across the active heating zone.
Highly uniform, homogenized beams reduce center overheating, insufficient edge temperature, localized burning, and surface-quality variation — helping to lower the risk of workpiece deformation, cracking, and batch-to-batch inconsistency. For composite curing, pre-weld metal preheating, coating preheating, and large-area surface treatment, this characteristic directly improves process stability and product consistency.
Large-Area Beam Output for High-Throughput Production
For large workpieces and high-speed lines, small-spot heating often requires multiple scanning passes, which adds motion-system complexity and creates temperature-continuity and repeatability issues. Vivlaser's high-power semiconductor laser heating system supports a variable square/rectangular beam from a few square centimeters up to a full square meter, enabling blanket heating of the target area.
A large-area beam reduces the number of scan passes, shortens heating time, lowers motion-system complexity, and improves overall production throughput. For large automated production lines, this large-area laser heating approach is easier to standardize, digitize, and automate.
Three Core Advantages for Industrial Heat Treatment
1. High Efficiency, Low Energy Consumption
The system delivers output power up to 20kW, with modular expansion to 40kW, 60kW, and higher power levels. Electro-optical conversion efficiency reaches over 50%, up to approximately 60%. Compared with the roughly 28%–30% efficiency of traditional fiber lasers, semiconductor laser heating reduces electricity consumption for the same process requirements while easing the load on cooling systems — well suited to long, continuous operation.
2. Beam Uniformity Above 95%
The combination of a square/rectangular large beam and >95% homogenization gives workpieces a smoother temperature distribution, reducing hot spots, edge over-burning, and localized temperature differences, while improving surface quality and downstream process stability.
3. Easy Integration and Customization
The system supports customizable beam shapes and sizes, with solutions designed around workpiece dimensions, fixture space, motion paths, and line cycle time. It can integrate with robots, AGVs, linear modules, roller conveyors, and PLC control systems.
