Supporting Inspiring Science and Technology

Universal Journal of Lasers, Optics, Photonics & Sensors

  • I would like to thank you first for this nice invitation at the conference LOPS 2021. The conference was very interesting, well organized and very inspiring for interaction and collaborations. I was impressed by the organization I found very efficient and flexible. The conference gave me the opportunity to present my research to a global audience creating an excellent synergy. Experience we have to do it again every year for sure! Looking forward to see you next year!
