Terahertz Josephson Fabry Perot Laser

在高Tc Bi_2Sr_2CaCu_2O_8单晶的本征约瑟夫森结中，我们成功地观测到了频率从350 GHz到750 GHz可调谐的THz辐射。最高频率可达近1 THz。一个热点区域，第一次观察到的低温扫描激光显微镜，归因于高的可调谐性的工作频率和600结的同步，这导致在一个非常窄的线宽。我们在《物理评论快报》和《物理评论B》上发表了三篇论文，并向《物理评论快报》和《物理评论B》分别提交了一篇论文。

In intrinsic Josephson junctions of high-Tc Bi2Sr2CaCu2O8 single crystals, we have successfully observed THz emission with tunable frequencies from 350 GHz to 750 GHz. The highest frequency is up to nearly 1 THz. A hot-spot area, for the first time observed by a low temperature scanning laser microscope, is attributed to the high tunability of the operation frequency and the synchronization of 600 junctions, which results in a very narrow linewidth. We published three papers in Physical Review Letters and Physical Review B, and submitted one to Physical Review Letters and one to Physcial Review B.
