Laser Beam Delivery Components
High Power Beam Dump
Overview
High Power Beam Dumps are engineered to safely absorb and dissipate laser energy in systems greater than 500 watts. Compared to our standard beam dumps, these models feature a more robust thermal design with larger absorbers and higher flow water cooling. The internal geometry minimizes backscatter and thermal loading, making them ideal for high-duty-cycle laser applications where elevated power levels demand higher dissipation capacity.

Applications
Applications
High-power beam dumps—also known as laser beam traps or laser beam blocks—are essential in industrial and research environments where continuous, high-power laser energy must be safely dissipated.
These units are commonly used in:
-
Automated laser welding and cutting cells, where beam termination is required during idle cycles or system checks
-
Laser testing stations to safely measure or redirect high-power beams during diagnostics
-
R&D labs and optics test benches that work with multi-kilowatt fiber or CO₂ lasers
-
Laser safety systems, providing a secure endpoint when beams are switched off or diverted
Their water-cooled design and robust absorber geometry make them ideal for handling long-duration exposure at high power levels without degradation.
Product selection guidance
Selecting a Beam Dump
High-power beam dumps are available in just a few configurations, making selection straightforward. Each part number indicates three things:
-
Aperture Size
Choose 38 mm or 50 mm depending on your beam diameter and system layout. A good rule of thumb is 1.5× your beam diameter. -
Absorber Material
Brass-coated cone — best for high-power infrared lasers (1064 nm–10.6 µm)
Copper — ideal for UV and visible wavelengths (355–532 nm) -
Cooling Type
Water-cooled, high-power system — designed for up to 20 kW continuous use
