Industrial VCSEL Heating Systems

Individually controllable emission zones for high-precision processing

Industrial VCSEL Heating 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.

Scalable power

Benefit from a scalable output power in the kW range.

High power density

Achieve a high process speed with irradiance of 100 W/cm².

Can be controlled precisely

Individual emission zones of the VCSEL beam source can be controlled independently of one another.

Simple integration

The robust and compact laser modules can be integrated easily into industrial systems and production processes.

Large-area heat treatment

Benefit from direct and homogenous heat treatment of large target areas, as well as from a high tolerance to back-reflections. Due to the high irradiance of over 100 W/cm², you can achieve high process speeds.

Flexible control of the heating profile

Enjoy the benefits of precise regulation of the heating power and free control of the heating profile in a longitudinal direction.

Fast joining of large plastic parts in furniture board production

Benefit from quick welding of large plastic parts due 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 of battery foils

Battery foils must be dried after the coating process to recover the solvent from the active material. Industrial VCSEL heating systems can take over this step, because laser sources based on VCSEL arrays are able to heat large areas with directed wavelength-selective infrared radiation.

FURTHER INFORMATION

E-Mobility: Pouch Sealing

Using VCSEL laser for the sealing/welding of pouch cells increase the quality and reduce the process time. A higher peel-off force can also be achieved.

FURTHER INFORMATION

Photovoltaics

VCSEL laser can support the Si wafer heating, as VCSEL heating modules enable a very homogeneous heating. Also the excellent local control of the temperature profile lead towards higher quality of the wafer.Typical heating rate is 45 degree / sec, but also faster heating rates (up to 260 degree / sec) can be achieved by using higher power.

Component generation using laser metal fusion

Additive Manufacturing

When large high parts should be printed, thermal gradients will occur in sintered parts. The stress can be minimized by VCSEL top heating.

Control software for VCSEL heating systems

Basic Driver Control Software

The basic version of the control software offers the function of manually controlling the laser channels of the VCSEL heating system and of setting the power.

Advanced Driver Control Software

The extended control software version is based on the basic version and offers additional functions such as temperature control or pulsing. In addition, time and performance profiles can be created. These can be used to vary the power of the VCSEL heating system during the processing time.

Lenses

The heat density of VCSEL heating systems can be influenced with additional lenses. The irradiance of VCSEL modules can be increased with positive lenses. The use of negative lenses decreases the irradiance of the modules.

Air Knife

The Air Knife can be used to keep spatter and steam away from the protective glass of the laser system. It creates a protective airflow in front of the laser.

Mounting bracket

Mounting brackets simplify the technical assembly of the VCSEL heating module.

Reduced irradiance

A VCSEL heating module with less tightly packed emitters and a defocusing lens can be used for applications requiring less irradiance.
