摘　　要：研究4-乙炔基-4′-[N,N-二羟乙基]胺基偶氮苯单体的光限幅效应,发现它对40ps脉宽,1064nm的激光呈现出较好的光限幅性能。并初步探讨了光限幅机理。In the paper, we studied the optical limiting properties of 4-ethynyl-4'-[N,N-dihydroxyethylamino]azobenzene and found that it posses good optical limiting property under 40 ps pulse laser at the wavelength of 1064 nm. Its optical limiting mechanism was investigated.The result shows that the optical limiting effect of 4-ethynl-4′-[N,N-dihydroxyethylamino]zobenzene is mainly originated from two-photo absorption.
