We have put together a list of the most frequently asked questions about the World of Photonics Congress for you on this page.

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.

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.

It depends.

Each scientific society is hosting its conference on its own digital platform. In order to access a platform, one needs to register with the specific society and purchase the ticket directly from that society. This ticket does not allow access to any of the other societies’ conference platforms.

However, each conference ticket does provide access to the World of Photonics Congress online platform, where each registered conference attendee can enter any society’s showroom and view the offered conference streaming. In addition, the World of Photonics Congress online platform offers:

  • Access to the World of Photonics Stage with selected scientific lectures from the conferences, award ceremonies, panel discussions and presentations on the markets and trends in photonics, including topics such as quantum technologies and photonic applications in infection control.
  • Access to LASER World of PHOTONICS’ Industry Days, including exciting webinars, interesting showrooms and many networking possibilities.

All of the photonics industry’s leading manufacturers, key players and decision-makers gather at the International Trade Fair for Optical Technologies – Components, Systems and Applications. Take advantage of this trade show as a source of new impetus and to make successful business contacts.

All important information about LASER World of PHOTONICS is available on the website.

LASER World of PHOTONICS trade fairs and their congresses are the most important marketplaces and think tanks for the global laser and photonics industry and those who use its products and solutions. They unite research and application and promote the use and further development of optical technologies. LASER World of PHOTONICS has been organized by Messe München International every two years since 1973. The World of Photonics Congress is held at the same time as the fair. It is the leading European scientific conference in the sector for photonics and laser research and one of the Top 3 in the world. The spin-off exhibition LASER World of PHOTONICS CHINA is the leading regional trade fair for optical technologies in China. It takes place every year in March. The network’s newest event, i.e. LASER World of PHOTONICS INDIA, was first held in September 2012. It is the regional trade fair for optical technologies in India and takes place every year. The fair is held alternately in Bangalore and New Delhi.
