Study on optical limiting properties in coordination polymers [Ag(L4)(NO3)·H2O]n
【摘要】 应用倍频Nd:YAG脉冲激光,在波长532nm、脉冲宽度为40ps和8ns的条件下,研究了配位聚合物[Ag(L4)(NO3)·H2O]n的光限幅特性。该聚合物的光限幅机理为激发态吸收,其皮秒光限幅特性优于纳秒光限幅特性。
【Abstract】 The optical limiting properties of a novel coordination polymers is studied by using frequency-doubled, Q-switched Nd: YAG laser with 40-ps and 8-ns pulses at a wavelength of 532nm. The optical limiting effect of [Ag(L4)(NO3)·H2O]n is stronger for ps than that of [Ag(L4)(NO3)·H2O]n for ns, and the excited-state absorption is the main mechanism of the optical limiting effect of the coordination polymers.
