VCSEL infrared power systems

High power for industrial heating

VCSEL infrared power systems

Beam sources based on VCSEL microlaser arrays deliver targeted large-area beams with a near-infrared output and are used in numerous industrial heating applications and production 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 heating applications and production processes.

Large-area heat treatment

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

Flexible control of the heating profile

Enjoy the benefits of precise regulation of the heating power and free control of the space heating profile due to flexible programming of emission zones.

Fast joining of large plastic parts in furniture board production

Benefit from quick welding of large plastic parts due to high irradiance in the well-defined heating zone. Integration is very easy due to the small dimensions of the module.

Local steel treatment in the automotive industry

With VCSEL heat treatment, it is possible to soften high-tensile steel parts selectively. This has many benefits, particularly in automotive production.
