Benefit from direct and homogenous heat treatment of large target areas, as well as from a high tolerance to back-reflections. Thanks to the high irradiance of over 100 W/cm², you can achieve high process speeds.
VCSEL infrared power systems
Beam sources based on VCSEL arrays are able to heat large surfaces with directed wavelength-selective infrared radiation. These VCSEL heating systems are used in numerous industrial heating processes. Due to direct irradiation of the treatment surface, significant cost benefits can be achieved compared to conventional laser systems, without expensive optics or scanner systems. The unique thing about the systems is that, in addition to the precise control and fast switch-over of the infrared output, the spatial heating profile can also be programmed as needed through independent control of small segments of the laser modules. The heating patterns can even change dynamically during operation. This enables unparalleled process flexibility
Benefit from a scalable output power in the kW range.
Achieve a high process speed with irradiance of 100 W/cm².
Individual emission zones of the VCSEL beam source can be controlled independently of one another.
The robust and compact laser modules can be integrated easily into industrial systems and production processes.
Fast joining of large plastic parts in furniture board production
Benefit from quick welding of large plastic parts thanks to high irradiance in the homogenously irradiated heating zone. Integration is very easy due to the small dimensions of the module.
Local softening of body steel in the automotive industry
VSCEL heating modules make it quick and easy to selectively soften high-tensile steel parts. This has many benefits, particularly in automotive production.
E-mobility: drying battery foils
The active material on the electrode foil must be dried after the recoating process. Industrial VCSEL heating systems can perform this step, because beam sources based on VCSEL arrays are able to heat large surfaces with directed wavelength-selective infrared radiation.
E-mobility: welding of pouch cells
Using VCSEL heating systems to weld pouch cells increases the quality of the welding results. In addition, the process time is reduced. The process is up to three times faster in comparison.
VCSEL lasers can be used in the semiconductor industry for heating the wafers for Rapid Thermal Processing (RTP). VCSEL heating modules make it possible to heat the wafers quickly and uniformly as the individual heat zones can be superbly controlled. Temperature increases of several hundred degrees Celsius can be achieved per second.
3D-printed high-volume components often have thermal gradients. This strain can be minimised by VCSEL top heating.
Photovoltaics: Fast Firing
VCSEL heating systems offer many advantages when burning in the contacts made up of silver particles on the top of the solar cells (firing). The systems do not need much space and the heat zones can be addressed individually. The high irradiance means that temperature increases of up to 1000 K/s can be achieved with a solar cell (fast firing). VCSEL heating modules also increase the energy efficiency and minimise costs.
The 2.4 kW VCSEL heating module is the smallest standard module. Like all modules, it has great cost benefits as the beam is directed straight at the application area without the additional use of optics or a scanner system.
The 9.6 kW VCSEL heating module is a standard module which is also used for directed, large-area heating applications.
This standard VCSEL heating system is the basis for numerous product variants as it can be adapted flexibly to customer requests. The width and therefore emitting area can be extended easily. The infrared output power can be up to several tens of kilowatts.
The 2.0 kW VCSEL heating module contains concentrating optics to divert the laser radiation to the joint gap in a targeted manner. This module is particularly suitable for applications in composite manufacturing.
The VCSEL heating systems can be easily adapted to customised requirements. Depending on the customer application, the correct configuration of VCSEL heating system is determined together.
The VCSEL module satisfies the specific requirements for the manufacture of furniture with welded and seamless edges to outstanding quality standards. This compact VCSEL laser source has horizontal zoning for varying edge heights. It is also particularly flat so that it is possible to get very close to the joining process.
This VCSEL module has a relatively low irradiance with a large width. This is why it is especially suitable for drying battery foils. Several modules can be arranged one after the other to create a longer drying path.
