Similar to the previous OPAL conferences, the 4th International Conference on Optics, Photonics and Lasers (OPAL' 2021) will incorporate three symposiums covering a broaden range in optics, photonics and lasers, and provide an excellent opportunity to exchange ideas and present latest advancements in these areas. The OPAL 2021 will be organized by the IFSA - professional, non-profit association serving for industry and academy more than 20 years.

The purpose of OPAL’ 2021 is bring together leading international researchers, engineers and practitioners interested on any of the optical related technologies. The conference will offer plenary and invited talks, contributed oral and poster presentations, special sessions, tutorials, and exhibitions of commercial products. Social and cultural events will also take place to foster networking among the participants in a friendly manner.

The previous OPAL’ 2018 (Barcelona, Spain), OPAL' 2019 (Amsterdam, The Netherlands) and OPAL' 2020 (Tenerife (Canary Islands), Spain) conferences have attracted many researchers and practitioners in the related fields, from around the world and all continents, who have presented the latest results covering theory, design, device technology and applications. We trust that you will find OPAL' 2021 conference professionally rewarding and stimulating as well as enjoyable.

The conference is focusing any significant breakthrough and innovation in optics, photonics, lasers and its applications:
