Precision Laser Micromachining Systems for R&D and Production

Did You Know?

Laser Micromachining Systems are a special class of laser material processing instruments designed for subtractive manufacturing. These machines allow precise removal of material from a surface of an object. The micromachining process is characterized by micrometer and often nanometer level resolution allowing controlled removal of layers of material to achieve the desired final product. Laser micromachining is often used for processing, metal, ceramic, glass and plastic objects. Advances in pulsed laser technologies including ultrafast (femtosecond and picosecond) laser systems lend themselves to utilization in state-of-the art laser micromachining systems enabling such advanced applications as micro-drilling high aspect-ration micro holes, engraving microchannels in microfluidic devices and controlled surface treatment on various materials to achieve special thermal and optical properties. Laser micromachining platforms are becoming increasingly commonplace with applications in biomedical device manufacturing, photovoltaics, nanomaterials, and other advanced high-technology domains. Many laser micromachining systems are custom built and allow configuration and outfitting with a desired laser source.

Frequently Asked Questions

Laser micromachining is a subtractive manufacturing process that utilizes precisely controlled laser beams to selectively remove material from an object with microscopic and often with nanometer level precision. The material is removed by the energy deposited by the laser pulses. While the mechanism of interaction of laser pulses with the matter can be thermal in some cases (mindful of the ultrafast laser) the interaction mechanism can be a lot more complex.

Overview of Laser Micromachining Systems

Laser Micromachining Systems are integrated platforms that combine a pulsed laser source, high-precision motion stages, beam delivery optics, and control electronics for material processing at the micrometer scale. These systems on FindLight are configured for drilling, cutting, structuring, and texturing of metals, polymers, ceramics, glass, and semiconductor substrates with minimal heat-affected zones.

Depending on configuration, Laser Micromachining Systems may incorporate UV, visible, or IR sources with nanosecond, picosecond, or femtosecond pulse durations. Typical system architectures include fixed-beam with XY stages, galvo-scan heads for high throughput, or hybrid solutions for complex patterns on both flat and 3D parts.

Typical Specifications and Capabilities

When comparing Laser Micromachining Systems, engineers typically evaluate:

  • Wavelength: Common options include 355 nm (UV), 532 nm (green), and 1064 nm (IR), selected according to material absorption.
  • Pulse duration and repetition rate: ns to fs regimes with kHz–MHz repetition for tuning ablation quality versus throughput.
  • Average and peak power: From a few watts to tens of watts average power, with high peak power for clean ablation.
  • Spot size and positioning accuracy: Spot diameters down to a few micrometers, with sub-micron stage resolution and bidirectional repeatability.
  • Work envelope: Typical travel ranges from tens to hundreds of millimeters, supporting wafers, foils, and small 3D components.
  • Process monitoring: Integrated cameras, fiducial recognition, and optional inline metrology.

These Laser Micromachining Systems are used in electronics (via drilling in PCBs, flex circuits, and IC substrates), medical devices (stent cutting, microfluidic channels), precision mechanics (micro-gears, nozzles, filters), and photonics (waveguide writing, fiber preparation, thin-film patterning).
