General questions about the World of Photonics Congress and the LASER World of PHOTONICS fair

The World of Photonics Congress is an umbrella event that unites several scientific conferences. The conferences are organized by the photonics industry’s leading scientific societies, and they are also responsible for registering participants.

For this reason, you can’t purchase a congress ticket at the World of Photonics Congress, but must register with one of the societies for the congress participation. All societies offer the same types of ticket at the same price. With this ticket, you can visit not only the Conference, but all conferences under the umbrella of the World of Photonics Congress. At the same time the ticket allows access to the LASER World of PHOTONICS trade fair.

In order to answer this question, a differentiation between speaker and listener is necessary.


Speakers must register at the conference where they have submitted their paper (lecture/poster).

If you have submitted a paper to more than one conference, in most cases it is only required to register for a congress ticket for one conference. However, this must be clarified individually with the scientific societies responsible for the respective conferences.


If you only want to attend the World of Photonics Congress as a listener, you can choose which conference you want to register for. In this case we recommend that you register with the conference or scientific society of which you are a member. For their members, the societies offer a membership discount on the Congress ticket. If you are a member of one of these societies, you should register with them to get this discount.

If you are not a member of one of these associations, you may choose which association you want to order your ticket from. All associations have the same ticket prices for non-members.

Ticket prices for the World of Photonic Congress are available here.

No, you only need one congress ticket! Your congress ticket includes:

  • Admission to all conferences at the World of Photonics Congress
  • Admission to the leading exhibition LASER World of PHOTONICS
  • Admission to the practice-oriented Application Panels that take place in the fair’s forums

One ticket allows you to move flexibly between the conferences at the congress, the trade fair in the exhibition halls and the lectures at the Application Panels to suit your own information and communication needs.

The scientific associations’ registration counters are located in the West Entrance of the Messe München trade-fair center. You can pick up your ticket and all congress documentation at the counter of the association with which you registered for the congress. Those who decide to attend at the last minute may also purchase a ticket at the congress.

Each exhibitor at LASER World of PHOTONICS receives one free World of Photonics Congress Ticket and up to five additional tickets at a reduced rate.

Please note: This applies only to audience members, and not to speakers! If you give a lecture at the congress, you definitely have to get your ticket from the scientific society that accepted your lecture.

The entire program of events at the World of Photonics Congress will be available in a database at this website in spring 2020.

We would be pleased to send you information about planning for the congress and about its highlights.
