The photochromic effect in poly(methyl methacrylate) (PMMA) fibre doped by 1,4-bis(2-methylstyryl)benzene is presented. The reversible photochromic effect of PMMA specimen and fibre has been checked using Nd-YAG (355 nm) laser. Under the UV, the photodimerisation process leads to switching into the coloured form and wide absorption band below 670 nm was observed. The kinetic of photoswitching process...
W artykule przedstawiono fazowanie w światłowodzie 19-rdzeniowym domieszkowanym Nd3+. Przeanalizowano wpływ parametrów materiałowych i geometrycznych aktywnego światłowodu 19-rdzeniowego oraz wpływ odchylenia od uzgodnionej fazy promieniowania na współczynnik jakości wiązki laserowej w obszarze dyfrakcyjnym dalekiego pola. Współczynnik jakości wiązki laserowej w wytworzonym światłowodzie wynosi BQF...
