Laser Beam Delivery Components

Standard Beam Dump

Overview

Haas standard beam dumps are designed to safely absorb and terminate unused laser beams during operation, alignment, or system idle states. These units use a coated absorber housed in a machined body to dissipate laser energy without reflection or backscatter. Available in multiple aperture sizes, they integrate directly into Haas beam delivery systems and can be installed at test ports, process head bypasses, or beam stops.

Built for long-term use in both production and lab environments, these beam dumps provide a simple, reliable way to safely capture excess or redirected laser energy.

Applications

Standard beam dumps — also known as beam traps, laser beam absorbers, or beam stops — are used in nearly every laser system to safely capture unused or redirected laser beams. Whether for safety, alignment, or process control, they prevent stray reflections and reduce the risk of equipment damage or operator exposure.

In industrial systems, beam dumps are often mounted at the end of a beam path, inside bypass lines, or at test ports. They’re used during system startup, shutdown, or when switching between beam paths to capture the full output of high-power lasers. They’re especially common in laser cutting, welding, drilling, and materials processing setups where beam redirection is part of normal operation.

In labs and R&D, beam traps provide a safe and convenient way to block the beam during optical alignment or prototyping. Their compact footprint and passive cooling make them ideal for mounting on optical tables, breadboards, or inside experimental enclosures.

Because they operate passively with no moving parts, Haas beam dumps are a dependable, low-maintenance solution for any application where laser energy needs to be safely terminated.

Specing a Beam Dump

1. Choose Aperture Size

Match the dump to the aperture series of your beam delivery system:

  • BD2-19

  • BD-25 

  • BD-38

  • BD-50

As a rule of thumb, choose an aperture that is 1.5× your beam diameter to prevent clipping or stray reflections.

2. Select Absorber Material

Haas beam dumps use internal conical absorbers designed to diffuse and absorb beam energy:

  • Brass-coated cones – Good for 1064 nm and IR wavelengths

  • Copper cones – Ideal for visible, UV, and green laser systems

Choose the absorber based on your wavelength range and desired durability.

3. Check Cooling Requirements

These are passively cooled models designed for moderate continuous power levels:

  • Air, ideal for power levels under 100watts

  • Water, ideal for power levels between 100watts and 500watts
    • For higher power beam dumps please see our high power beam dump product line
