摘　　要：纳秒级脉冲激光对战场中广泛使用的光电传感器构成了严重威胁。光限幅材料在阻止强激光通过的同时,不影响低能量信号光的通过,是目前激光防护领域的研究热点。针对可见-近红外波段光电传感器强激光防护应用需求,在金属酞菁化合物基础上,基于增强其共轭体系电子云密度的设计思想制备了一种新型高性能光限幅材料——四枯丁苯氧基氯代酞菁铟,并对其进行了测试表征。瞬态吸收光谱实验表明,四枯丁苯氧基氯代酞菁铟具有很强且长寿命的激发态吸收。光限幅性能测试证明其光限幅启动阈值为8 mJ/cm^(2),光限幅阈值为0.06 J/cm^(2),损伤阈值大于4 J/cm^(2),当输入能流达到3 J/cm^(2)时,光限幅器件透过率下降到6%。由测试结果可以看出,该材料光限幅启动阈值及光限幅阈值低,损伤阈值高,可见-近红外波段线性透过率高,具有优异的光限幅性能,在光电系统激光防护中具有较高的应用前景。Nanosecond pulsed lasers pose a serious threat to photoelectric sensors widely used in the battlefield.Optical limiting materials not only prevent the strong laser from passing through,but also do not affect the low-energy signal light,which is a research hot-spot in laser protection field at present.To meet the application requirements of strong laser protection for optoelectronic sensors in visible-near-infrared band,based on metal phthalocyanine compound and the design idea of enhancing the electron cloud density of its conjugated system,a new type of high-performance optical limiting material,tetra(4-(2-phenylpropan-2-yl)phenoxy)indium chlorophthalocyanine,is prepared and it is tested and characterized.Transient absorption spectrum experiments show that tetra(4-(2-phenylpropan-2-yl)phenoxy)indium chlorophthalocyanine has strong and long-life excited state absorption,The optical limit performance test shows that the optical limit start threshold is 8 mJ/cm^(2),the optical limit threshold is 0.06 J/cm^(2),and the damage threshold is greater than 4 J/cm^(2).When the input energy current reaches 3 J/cm^(2),the transmitance of the optical limiting device decreases to 6%.It can be seen from the test results that the material has low optical limit start threshold and optical limit threshold,high damage threshold and high linear transmitance in visible-near-infrared band,which indicate that it owns excellent optical limit performance,and has a high application prospect in laser protection of photoelectric system.
