Micromachining with lasers and liquids

Lidrotec - Laser Hydro Technologies

Microprocessing utilizing lasers and liquids: fast, precise and versatile

Material processing with ultrashort laser pulses is currently one of the most innovative production and manufacturing processes, and allows high-precision cutting, drilling and structuring of a wide variety of materials.

We aim to expand the application potential of ultrashort pulse laser processing through an innovation:

We efficiently use liquids in the laser processing zone, which greatly cools the workpiece and removes ablation products such as particles. As a result, the processing speed can be increased whilst maintaining high precision and achieving significantly cleaner surfaces.

Using our years of experience in the field of micromachining with ultrashort pulse lasers in liquids, we are currently working on building a robust industrial laser system. The implementation of this project is supported by the funding of the „EXIST-Forschungstransfer“ (BMWi).

If we have aroused your interest, please contact us by phone or e-mail.

Below you will find application possibilities and further advantages of laser micromachining in liquids.

Comparison of the state of the art with our method

The schematic illustrations show the differences between ultrashort pulse machining in liquids and conventional machining in a gas environment. At high power and very short repetition rates, the following evidenced phenomena can be observed:

In gaseous environment

Thermal defects

Particle deposits

Surface defects

Use of liquids

Effective cooling

Removal of particles

Increasing precision



Fast, clean, functional and safe - the advantages are obvious

The use of liquid has four decisive advantages compared to processing in gas atmospheres, so that it can be used for multifunctional purposes.

  • Kühlmedium - schnell


    The heat transfer from the workpiece to the liquid is much greater than with gases. Higher repetition rates and pulse energies can be used for machining, therefore allowing a high process speed.

  • Spülmedium - sauber


    Removed micro- and nanoparticles are carried away by the liquid and therefore cannot attach to the surface. In addition, adhesion forces are reduced and the removal of contamination is simplified.

  • Prozessmedium - funktional


    Physicochemical interactions between the material, the laser beam and the liquid can be used to functionalize the sample surface (e.g. making it hydrophobic).

  • Sicherheitsmedium - sicher


    In addition to the effective binding of nano- and microparticles, liquids absorb soft X-rays much more effectively than air. The liquid thus serves as an additional safety feature for the health of the user.

Application fields

Opportunities and benefits of LIDROTEC’s technology

Laser processing in liquids offers a lot of potential for a variety of companies in the processing industry. The process is predestined for applications with the following requirements:

High quality
Burr-free and sharp cutting edges with high precision

Free from surface contamination

Minimum heat input
Machining of thin and heat sensitive workpieces

High aspect ratio
High ratio of depth to width of a structure

High process speed through active cooling of the workpiece

Free forms and geometries selectable

Targeted removal of certain materials in multilayer systems

Comprehensive material selection
Metals, semiconductors, ceramics, glasses, composites or polymers

Structural or chemical adaptation of the surface properties

Cutting, drilling, structuring and functionalising in one process




We, as the team behind LIDROTEC, have over 15 years of experience in laser material processing and would like to create new and better technologies.
