Nonlinear optical and optical-limiting properties of Azobenzene liquid crystal polymer☆
Optics Communications 203(2002)159-162,-0001,():
The nonlinear absorption coefficient b of Azo (Azobenzene) liquid crystal polymer (LCP) was measured by using open aperture Z-scan technique with 10 ns, 532nm laser pulses.The value of b is 9.02cm/GW. The optical limiting (OL) response of Azo LCP in tetrahydrofuran (THF) was measured also by use of the Q-switched (10 ns) secondharmonic generation Nd:YAG pulse. We attribute the nonlinear absorption and OL property of Azo LCP to TPA effect at 532 nm.2002 Published by Elsevier Science B.V.
