Fascinating precision

The 21st International Symposium on Laser Precision Microfabrication (LPM 2020) was hold from June 23-26. Although the event was planned to be realized in Dresden (Germany), due to the pandemic situation the conference was performed virtually, with 216 participants presenting their work in 3 parallel sessions.


In addition to the plenary, invited and regular talks, the conference was also accompanied by a virtual exhibition as well as a poster area, allowing the participants to a truthfully exchange of ideas. LPM is recognized as one of the most important international events on laser-based micro and nano technology, where the most advanced developments and recent trends in laser applications for fine and precise fabrication of diverse materials are discussed among people coming from both academia and industry. LPM2021 will be held at Hirosaki-city, Japan. 

The international LPM community was not deterred by the new circumstances, making the first virtual LPM based on the online system developed by DGM a complete success. Over the four days of the symposium, 216 international participants from 24 countries exchanged information in three parallel lecture rooms in 145 lectures and 34 poster presentations.

From those contributions the whole plenum voted for both best Poster Award and Oral Talk Award by students participating at LPM2020.

The special challenge of the time difference was also solved with a specially adapted program run as well as a media library in which all lectures were recorded and subsequently retrievable in the respective time zone and was gratefully accepted by the participants.

Furthermore the Digital Abstract Booklet is still available for download on the LPM website.


In addition, DGM offered its self-developed concept of a virtual trade fair for the first time at LPM2020, which was accepted by exhibitors such as Amplitude, Asphericon GmbH, Femtika, Femtosurf, InnoLas Laser GmbH, Lumentum, MKS Instruments, TOPAG, Toptica.


Looking into the future the Symposium Chair announced that the „22nd International Symposium on Laser Precision Microfabrication“ will be held in the beautiful city of Hirosaki, Japan, from June 8–11, 2021. Furthermore the 2022 edition of the LPM will finally take place in Dresden, Germany, the initial location for this year’s event.
