The paper reports synthesis and co-crystallization of 5 co-crystal of 4-nitrophenol (4N) with five different monoand diaminopyridines (4-aminopyridine (4AP); 3,4-diaminopyridine (34DAP); 2-amino-6-methylpyridine (26MAP); 2,6- diaminopyridine (26DAP); 2-aminopyridine (2AP)) resulted in five adducts with the molar ratio of components 2:1 in final compounds. X-ray analysis confirms the non-centrosymmetric packing of obtained compounds. Two compounds crystallize in the polar acentric P21 and three compounds crystallize in acentric orthorhombic Pna21 space groups. The comparative studies on the laser induced multiple and single shot damage thresholds of named crystals were carried out using radiation of 1064 nm from Nd:YAG laser with pulse width 10 ns. Obtained results show good laser-induced singleshot and multiple-shot damage threshold values for all studied co-crystals and are found up to 3.64 GW/cm2 and 1.77 GW/cm2 respectively.
Kinetics of polymer microelements growing on the top of optical fiber with use of different photoactive additives (Rodamine B, Coumarin) was studied. Consequently, the technological principles of production of polymer self-adjoint microelements were founded
