Experimental research of simultaneous tunable chromatic dispersion (CD) and adaptive polarization mode dispersion (PMD) compensations in optical fiber communication system was reported. Two different nonlinearly chirped fiber Bragg gratings fabricated thr
A set of system based on personal computer for the bi-directional reflectance distribution function (BRDF) measurement was developed, whose laser wavelengths cover 0.6328, 1.34, 3.39, and 10.6 μm from visible to infrared. Stray light in BRDF measurement s
美国汉密尔顿麦克马斯特(McMaster)大学的研究者制作了一台二氧化碳激光器,在4.3微米波长处其峰值功率为1000瓦,平均功率为50毫瓦。据兹努汀斯(T. A. Znotins)和他的同事说,这种激光器用普通的10微米CO2激光泵浦,“采用现有的CO2激光工艺易于按比例放大”。兹努汀斯指出,包括激光化学在内的各种应用都希望有强的中红外辐射源;4.3微米处在氟化氘和一氧化碳激光器的输出波长之间。
