Laser Beam Profiling

Noninterceptive Beam Profiling of High‐Power Industrial Lasers

High‐power 1 — 100 kW industrial lasers typically undergo thermally‐in‐duced optical effects that change the laser beam and laser beam delivery to the work piece. Knowledge of any changes such as focal shift may be important for particular welding or cutting processes. Conventional beam profile diagnostic methods are not practical and fall short at such high powers. A new profiling technique that uses Rayleigh scatter from…

Laser Micro Processing

The Next Generation of Ultra‐short Pulsed Laser Micro Processing

Ultra‐short pulsed (USP) laser processes for industrial applications put high demands on the machine concept: The need for high flexibility in the machine configuration, constant machining results over long process cycles and efficient laser processes to reduce processing costs require a holistic approach in the design of a laser micro machine. For the development of a new laser machine for USP laser micromachining, the…

Fiber Lasers

Need for Seed

In recent years, high power lasers have become a matter of course. A superior laser source can be described by its brilliance, a combination of beam quality and output power, its versatility in terms of pulse generation, its size and weight, its stability as well as reliability and by its total cost of ownership. Traditional high power lasers use gaseous gain media like carbon dioxide or crystals like yttrium aluminum…

Laser Material Processing

Orbital Laser Manufacturing

For many types of work pieces, a laser processing alongside the circumference of the work piece has to be carried out in mass production. Elongated work pieces with a 3D shape or even endless and continuously produced work pieces like tubes and profiles are hard to handle with respect to a static laser beam, because they either cannot be rotated at all or they are too complex and bulky to be handled at all. …

Additive Manufacturing

Metal Laser Melting

Metal laser melting is enjoying growing interest. The process has made the leap from being used for rapid prototyping to developing into a recognised manufacturing technology. In the past, it was primarily used to produce prototypes but today, additive manufacturing is used in many industries for (small and medium) series manufacturing. Toolcraft is offering completely new possibilities in metal laser melting that are…

Lasers for Medical Devices

Laser‐based Preparation of Biological Tissue

Histological analysis of biological specimens is the gold standard and mandatory if medical products like implants shall get approval according to FDA (USA), The Act on Medical Devices (Germany) or others. Unfortunately, most of these specimens with implants are extremely difficult to process due to the hardness of the materials. Femtosecond lasers are known to process a variety of materials without any significant thermal…
