Our laser systems combine various laser sources and processing technologies to produce precision parts in all three dimensions. From feasibility analysis and process development to series production, we offer tailor-made solutions for your manufacturing tasks. With experience, technical expertise and state-of-the-art equipment, our application engineers optimize every parameter until the result exactly meets your requirements.
We use various laser sources to produce precise cuts in 2D, 3D and pipe geometries. The focused laser beam enables narrow kerfs and clean edges - even with intricate contours and challenging materials.
Our laser technology joins metals and material combinations with high strength and precision. The process works without contact, with minimal heat input and produces tight, clean weld seams for your precision parts.
Our laser drilling processes produce precise micro holes with maximum reproducibility - fast, wear-free and gentle on the material. Ideal for applications where the smallest diameters and tight tolerances are required.
LLT Application stands for laser precision machining at the highest level. Whether cutting, welding, drilling or ablation – our processes guarantee micrometer-precise results, reproducible quality and maximum process reliability. State-of-the-art laser sources, many years of experience and a deep understanding of material properties enable economical and gentle processing of even the most challenging materials.

Our laser systems are equipped with a wide variety of laser sources and components. This allows us to process your precision components using various methods and in all three dimensions.
Precision cutting is a thermal cutting process in which a focused laser beam combined with a coaxial process gas flow produces a very narrow cut. Through a relative movement between the laser beam and the workpiece, flat parts as well as tubes and three-dimensional contours can be realized with high precision and kerfs of 10 µm and smaller.
The following variants of laser cutting are possible with our laser systems or as part of our contract manufacturing:
Laser precision welding uses a focused laser beam as the energy source. The joining partners are firmly joined by a relative movement between the laser beam and the workpiece. The machining process takes place under shielding gas, such as argon or nitrogen, which prevents oxidation of the component surfaces. Depending on the process gas, material and laser parameters, the joining process is often determined by pure heat conduction, and in deep welding applications by the so-called keyhole effect.
When conventional welding processes reach their limits, we can help you with our laser systems and contract manufacturing. For 2D and 3D components as well as for cylindrical precision components, different weld seams and geometries with welding depths of up to 2 mm can be realized using the following processes:
Our laser systems are equipped with a wide variety of laser sources and components. This allows us to process your precision components using various methods and in all three dimensions.
Laser drilling is a non-chipping process in which the material is heated, melted and vaporized. The ablated material is blown out of the hole using the process gas. Pulsed lasers are often used, the energy input of which can be precisely regulated. In addition to a wide variety of shapes, holes with different depths can also be produced. This allows through-holes or blind holes with diameters of less than 5 µm, the conicity of which can also be influenced by corresponding laser parameters.
Depending on the intended drilling depth, the conicity of the hole and the processing speed, a distinction can be made between different laser drilling processes. With our laser systems and our contract manufacturing, we can offer you the following processes:
During laser ablation, material is vaporized layer by layer. The ablated layer thicknesses range from a few nm to a few µm. The process also allows thicker materials to be processed. Due to the low heat input, it is also referred to as cold processing. The thermal stress for the component is minimal. The use of femtosecond lasers also prevents residues in the form of molten material on the component surface. The ultrashort pulse laser also enables the processing of special materials such as glass.
We mainly use ultrashort pulse lasers for laser ablation. However, fibre lasers are of course also available for our contract manufacturing and plant construction in order to implement various ablation processes:
As a service provider and partner to customers in high-tech industries such as medical technology, we are always aware of our responsibility for the products that leave our company. This is why our quality management is not an end in itself. Rather, in addition to meeting customer requirements, quality primarily means freedom from defects. And under certain circumstances, this ensures the health and integrity of lives.
The quality management system applies to all areas of the LLT application and aims to continuously improve the quality of our services and products for the benefit of our customers. This also means learning from our own mistakes, i.e. recognizing them at an early stage and initiating appropriate countermeasures.
The effectiveness and application of the quality management system is regularly checked as part of internal audits, but also externally by customers or by our certification body (TÜV Hessen).
We support you in the economical manufacture of your products and accompany you from your initial product idea through process development and series production in our company to your own laser production system.
Laser micromachining is contactless, gentle on the material and highly precise. In contrast to mechanical processes, there is no tool wear and no deformation of the workpiece. As a result, the finest structures, smooth cutting edges and precise contours can be achieved - even with temperature-sensitive or difficult-to-machine materials. LLT Application thus achieves reproducible results with the highest surface quality, both for individual parts and in series production.
We use various laser sources in our laser applications - including fiber lasers, Nd:YAG lasers and ultrashort pulse lasers. Our engineers select the optimum technology depending on the application and material: Fiber lasers for high cutting speeds in 3D laser cutting, ultrashort pulse lasers for micrometer-precise ablation processes or Nd:YAG lasers for precise welding of sensitive precision parts. Each process is perfectly tailored to the task at hand.
Our laser processes are fully monitored, documented and designed for maximum process stability. We guarantee consistently high quality through automated positioning systems, constant laser power and regular calibrations. In addition, a certified quality management system checks every production run to ensure that every precision part meets the specified tolerances exactly.
Yes, we develop individual laser processes for many customers - from parameter optimization to complete process development. In our application laboratory, we test materials, define laser parameters and create feasibility studies. This results in tailor-made processes with which special requirements for cutting quality, structuring or surface treatment can be precisely implemented.
