Pavel A. LOIKO is a Chargé de recherche CNRS (Section 17 - Chimie des matériaux, nanomatériaux et procédés) at the Centre de Recherche sur les Ions, les Matériaux et la Photonique (CIMAP), UMR 6252 CEA–CNRS–ENSICAEN, Université de Caen Normandie, France. 

He is a member of the OML team (Optique, Matériaux et Lasers). He is also a member of the conseil d'unité of CIMAP.

He obtained his PhD in Optics from Belarusian State University (Minsk, Belarus) in December 2012. In October 2023, he was awarded the Habilitation à diriger des recherches (HDR) from Université de Caen Normandie.

His research focuses on the development of novel functional optical materials for coherent light sources (visible to mid-infrared), including ultrashort-pulse lasers. His expertise includes structure–property relationships, advanced spectroscopy of rare-earth and transition-metal ions, novel laser transitions / pumping schemes, and integrated optics (waveguide sources), across materials such as single crystals, transparent ceramics, glasses, fibers, and epitaxial thin films. 

He currently serves as a Topical Editor for Journal of the Optical Society of America B (JOSA B) and Applied Physics B: Lasers and Optics, and a Scientific Committee Member for the international conferences Europhoton 2026 and Advanced Solid-State Lasers 2026.
