High-power terahertz electromagnetic wave emission from high-T(c) superconducting Bi2Sr2CaCu2O(8+δ) mesa structures.
In this paper, we report intense electromagnetic wave emissions generated by the rectangular mesa structure of intrinsic Josephson junctions with high-T(c) superconducting Bi2Sr2CaCu2O(8+δ). The radiated power is an order of magnitude stronger than that of the previously observed power of a few μW. Two emission regions, reversible (R-type) and irreversible (IR-type), with comparable intensities...

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
Applications using high-Tc superconducting terahertz emitters
Using recently-developed THz emitters constructed from single crystals of the high-Tc superconductor Bi2Sr2CaCu2O8+δ, we performed three prototype tests of the devices to demonstrate their unique characteristic properties for various practical applications. The first is a compact and simple transmission type of THz imaging system using a Stirling cryocooler. The second is a high-resolution Mich...
متن کاملHigh duty cycle and continuous terahertz emission from germanium
In the far-infrared wavelength or terahertz frequency range ~1–10 THz! there are a wide variety of potential applications for compact and tunable lasers. High resolution spectroscopy is relevant to such diverse fields as astronomy, biochemistry, and physical chemistry. Objects of interest include star-forming regions in the universe, heavy ligands in biomolecules which vibrate and rotate with a...
متن کاملTerahertz emission from (100) InAs surfaces at high excitation fluences
The radiated terahertz field from (100) InAs surfaces under excitation at fluences of millijoules per centimeter squared has been studied in detail in order to identify the main generation mechanism. We find that the terahertz emission depends strongly on pump polarization, and that the predominant emission mechanism appears to be the surface nonlinear optical response of the InAs crystal. A sa...
