8 Design Considerations for Direct Diode Heating Systems

Direct diode heating in industrial applications refers to heating specific regions of a material surface with a semiconductor laser diode. This is as opposed to a fiber or solid-state laser or other non-laser heating methods. In a previous article we described reasons why direct diode heating is more effective than older methods such as IR lamps, microwaves, or forced air. One of the primary advantages of diodes is their flexibility—virtually any aspect of a diode laser heating system can be designed and optimized for performance and cost. Below are 8 factors to consider when choosing a laser diode for a direct diode heating system.

Six Advantages of Direct Diode Heating for Industrial Laser Applications

Most manufacturing processes require some form of surface heating, but many products cannot be heated directly. Examples include shrink-wrapping, bonding, and annealing. Existing solutions include IR lamps, microwaves, and forced air. None of these methods are ideal—they can be imprecise, inefficient, or even a safety concern. Diode infrared lasers are emerging as an excellent non-contact method of heating surfaces. "Direct diode heating" refers to heating specific regions of a surface with patterned laser irradiation.
