激光波长调谐对于在压力检测、 强电场监测、 痕量气体探测以及可见光通讯领域中提高动态波长分配效率起着重要作用. 拉曼散射是一种具有频移特性的非线性光学效应, 这表明拉曼散射可能是一种实现激光波长调谐的可行方法. 在本文中, 我们发现在特定的测试结构下, 氮化铝的A1(TO)模式对应的散射光具有线偏振特性. 此外, 通过温度调制, 我们在氮化铝中实现了高精度的散射光波长调谐. 基于实验结果, 具有高热导率和高稳定性的氮化铝可能是一种实现激光波长调谐的良好载体.

Single crystals of Ammonium acid phthalate have been grown using the slow evaporation technique. A single crystal of good quality was harvested in a period of 30 days. Different characterization studies were carried out for finding its suitability in device fabrications. The lattice parameters were found from single crystal X-ray diffraction analysis. The grown crystal crystallized under orthor...
