Laser Beam Delivery Basics

Introduction

A laser beam delivery system is designed to transport the laser beam safely and accurately to the workpiece while maintaining stability and efficiency in an industrial environment. Several factors influence the design of these systems, including the type of laser process, material properties, processing speed, reliability, and beam characteristics such as wavelength, polarization, and pulse properties.

Manufacturers develop each component of a beam delivery system to maximize performance for specific applications. Haas Laser Technologies specializes in advanced beam delivery solutions designed for industrial laser processing. This paper explores the key components of laser beam delivery systems and their applications across different laser types.

Understanding Beam Delivery Systems

Laser beam delivery systems are typically categorized into two main types, each tailored to enhance performance for specific applications.

Transmissive Beam Delivery Systems (Fiber Delivery)

Also known as fiber-optic beam delivery, this system transmits the laser beam through a specialized fiber-optic cable, offering flexibility for high-power laser applications. It is commonly used with short-wavelength systems around 1um. The fiber's core diameter and material composition are carefully chosen to maintain stable and consistent beam quality.

Reflective Beam Delivery Systems (Mirror Optics)

Reflective beam delivery systems rely on high-quality mirrors to guide the laser beam to the workpiece. This approach is ideal for applications requiring high power and long-distance beam delivery while minimizing energy loss. Haas Laser Technologies provides engineered mirror-based systems that maintain beam integrity across various laser wavelengths.

Key Beam Delivery Components

A well-designed beam delivery system incorporates various components that contribute to accuracy, reliability, and efficiency. Haas Laser Technologies offers a comprehensive range of solutions designed for industrial applications.

Beam Directing Components

These components control the laser beam’s path from the source to the workpiece.

• High-Performance Mirrors – Redirect the beam with minimal loss.
• Beam Splitters – Divide the laser beam into multiple paths for parallel processing.
• Adjustable Kinematic Mounts – Fine-tune alignment for improved accuracy.

Beam Enhancement & Positioning Components

To maintain beam quality and adapt to various applications, these components adjust the beam’s size, shape, and position:

• Circular Polarizers – Convert linear polarization to circular polarization, improving energy distribution for cutting and drilling.
• Collimators & Spatial Filters – Control beam divergence and clean up stray energy.
• Autofocus Systems – Adjust focal point dynamically to maintain optimal performance.

Beam Position Viewing Components

These tools help monitor and verify beam alignment, ensuring proper positioning during operation.

• Closed-Circuit TV (CCTV) Systems – Provide a remote view of the laser beam and workpiece.
• Capacitive Sensors – Measure the distance between the laser head and the workpiece, providing real-time feedback for focus adjustments.

Laser Process Heads & Accessories

The laser process head focuses and directs the laser beam onto the workpiece. Depending on the application, Haas Laser Technologies provides both transmissive and reflective process heads. These process heads may incorporate:

• Gas Jet Systems – Assist in material processing by directing gas flow thorough the cut kerf.
• Protective Windows & Lens Holders – Safeguard optics from contamination.
• Adaptive Mounting Systems – Allow for easy integration into automated and manual setups.
