AVONISYS WATERJET GUIDED LASER

Nearly 3 decades after the first water guided laser was unveiled, Avonisys developed and industrialized a completely new a waterjet laser system from scratch, tailored for 24/7 heavy duty applications that require reliable micro-precise laser machining. We have put a lot of effort in making the waterjet guided laser system particularly robust and easy to maintain in order to adapt it to todays industrial performance requirements. 


Laser energy guided inside a thin waterjet

In 1986, the first laser beam guided by internal reflection inside a liquid column was unveiled (Aesculap–Werke AG, Germany). This working principle is an effective way to transport laser energy over a longer distance to a work piece, while maintaining a constant small “tool” diameter (read more). Today, waterjets of as small as 0.03mm in diameter can be used. These are generated using waterjet nozzles similar to those applied in regular waterjet cutting systems. In a nutshell the main benefits of the waterjet guided laser are:


     High quality cutting surfaces without burr

     Parallel cuts without heat impact (HAZ)

     No focus compensation required

     No process forces applied to work piece

     High aspect ratio micro slot cutting

     Deep micro-hole drilling

     Broad process window

Technology Principle

The energy of the laser focus is coupled into a very thin waterjet, where it is guided to the work piece by total internal reflection. The energetic diameter of the laser beam remains constant over a large working distance of up to several centimetres. Typical tool diameters of the waterjet are 0.03 - 0.08 mm.

High Power Laser Coupling

Our laser head & waterjet coupling system are designed for efficient high energy transmission of the laser beam, yet without impacting the cutting nozzle or the laser window. Our proprietary laser in-coupling method ensures that for each cutting nozzle diameter and each laser setup the perfect coupling point is set.


    High power transmission

    Long consumable lifetime


Air-Jet Technology

Air-Jet is a high volume flow of air that is mechanically separated from the waterjet. Through the use of Air-Jet, deep work piece cavities can be machined highly effective. Furthermore Air-Jet mitigates the effect of water back-reflections as well as build up of droplets, which can otherwise impact cutting results. 


    Effective waterjet protection

    Enables machining inside cavities


Range Extender

For certain applications, Avonisys offers a stretched version of its Air-Jet module. Using this working distance range extender, the waterjet is mechanically encapsulated and protected over a longer distance. This way, complex parts that require a particularly long standoff distance can be machined highly effective.


    Enables long standoff distances

    Increased protection of liquid-jet


Simple Maintenance

Our laser systems are designed in such way that quick access to all critical components is guaranteed. We have incorporated quick releases to core parts such as the laser coupling unit, the cutting nozzle and laser transmission window. Parts are rapidly exchanged and the system is back online in just minutes.


    Quick maintenance

    System back online in minutes


Strong Know-How & IP

Through own fundamental research as well as IP acquisitions, Avonisys meanwhile hold a comprehensive patent portfolio of 20+ patents and patents pending in key regions, such as the USA, Europe, Korea and China. Therefore Avonisys can offer very comprehensive, independent and high-end technological solutions.

How waterjet laser technology is applied

  • (1) Laser energy is guided to the work piece inside a hair-thin cylindrical waterjet
  • (2) Multiple passes of the laser (similar to mechanical milling) ablate the material and create parallel slots of as narrow as 0.04-0.05mm and up to for example 20mm deep
  • (3) Avonisys waterjet laser technology allows highly effective processing of complex 3-dimensional work pieces 
  • (4) Machining the work piece in multiple axis simultaneously allows to create arbitrary slot or hole geometries

Technology benchmark

EDM / Wire-EDM


  • Heat impact to work piece = change of material properties
  • Only for conductive materials
  • Not suitable for (blind) slots as narrow as the Avonisys process (<0.08mm width)

Waterjet cutting


  • High water pressure can cause chipping and burr
  • Cutting kerf is 5-10x wider than Avonisys process
  • Typically high consumption of cutting nozzles due to abrasive additives
  • Peck hole required

Dry laser cutting


  • Beam waist defines achievable cutting kerf
  • Heat impact to work piece = change of material properties
  • Typically causes burr on back side
  • Precise focus distance required
  • Can deform thermally sensitive parts

Avonisys waterjet laser


  • No HAZ or burrs
  • Ultra narrow kerf >0.03mm
  • High aspect slots < 400:1
  • Broader process window than dry laser (even USP)
  • Can cut  non-conductive materials
  • No focus distance compensation required
  • No deformation of thermally sensitive materials
