"Photonics exhibition with its extensive conference programme has long been the main event of the Russian laser and optical industry, the main working platform for its market participants. The past year demanded from many organisations in this industry to actively restructure their activities, search for new suppliers and partners, build new logistical chains, obtain new approvals and protections. In general, they have successfully coped with all that. Proof of this is the rich display of Photonics 2023 with a large number of new developments and a hundred and fifty reports at the 11th Congress of Photonics Technology Platform on such developments and their applications".
