Chromophores in azo dyes are optically active and play an important role in modifying the optical nonlinear properties. Methyl orange (MO), an azo dye, has been chosen to dope with l‐arginine monohydrochloride (LAHCl), in order to tune the nonlinear optical properties. Pristine and MO doped LAHCl single crystals are grown by slow solvent evaporation method at ambient conditions. The grown crystals are confirmed by powder X‐ray diffraction and Fourier transform infrared studies. The crystals are subjected to linear and nonlinear optical characterizations. Decrease in optical band gap with increase in refractive index and birefringence are attributed to the increase in net macro‐polarizability of the doped LAHCl. Both pristine and MO doped crystals exhibit reverse saturable absorption (RSA) in Z‐scan measurements. The samples show optical limiting behavior under laser irradiation at 650 nm. The chromophore of MO has a significant role in enhancing RSA and optical limiting behavior of LAHCl.

甲基橙染料掺杂的1-精氨酸单盐酸盐（LAHCl）单晶的反向饱和吸收和光学限幅应用
偶氮染料中的发色团是光学活性的，并且在改变光学非线性特性中起重要作用。甲基橙（MO），偶氮染料，已被选定为与涂料升-精氨酸一盐酸盐（LAHCl），以调节非线性光学性质。原始和钼掺杂的LAHCl单晶是在环境条件下通过慢速溶剂蒸发法生长的。生长的晶体通过粉末X射线衍射和傅立叶变换红外研究证实。对晶体进行线性和非线性光学表征。随着折射率和双折射的增加，光学带隙的减少归因于掺杂的LAHCl的净宏观极化率的增加。原始和MO掺杂的晶体在Z扫描测量中均显示出反向饱和吸收（RSA）。样品在650 nm的激光照射下显示出光学极限行为。MO的发色团在增强RSA和LAHCl的光学限制行为中具有重要作用。
