International Conference Laser Optics takes place biennially in Saint Petersburg, Russia. This is a traditional scientific event in the field of laser physics, optics, and photonics. 21st International Conference Laser Optics (ICLO 2024) will take place on 1-5 July 2024 at the Moskovskiye Vorota Hotel - St. Petersburg

ICLO 2024 technical program includes plenary and parallel oral and poster sessions over five days. Distinguished plenary and invited speakers will present the state-of-the-art of laser physics, photonics and optical engineering.

Additionally, the Conference will host the 8th International A.M. Prokhorov Symposium on Biophotonics.

The scope of ICLO 2024:

  • Solid State Lasers
  • Semiconductor Lasers, Materials and Applications
  • Lasers and Systems for Imaging, Green Photonics and Sustainability
  • High-Power Lasers
  • Free Electron Lasers
  • Super-Intense Light Fields
  • Optical Nanomaterials
  • Quantum Optics
  • Nonlinear Photonics
  • Laser Beam Control
  • Lasers for Space Applications
