9361755 Manasson Physical Optics Corporation (POC) proposes to develop a novel high- power, low-loss, hollow-fiber waveguide for the delivery of C02 laser energy. The waveguide's cladding will be made of materials with refractive index n 1 in the CO2-laser (10.6 micron) wavelength band. A unique feature of the proposed approach is that the optical properties of the cladding material can be easily varied because of the nature of the materials employed. Thus, by slightly changing material composition, the operating wavelength of such fibers can be "tuned," making this a generic technology with broad applicability to the transmission of IR energy from any source. According to POC's preliminary ca1culations, the proposed design will result in a fiber having transmission losses that are orders of magnitude lower, at 10.6 microns, than the lowest losses reported for other fibers. It is at this wavelength that we propose to first demonstrate this technology. ***

9361755 Manasson物理光学公司（POC）提出开发一种新型的高功率、低损耗、中空光纤 用于输送CO2激光能量的波导。波导的包层将由在CO2激光（10.6微米）波长带中具有折射率n 1的材料制成。所提出的方法的一个独特特征是，由于所采用材料的性质，包层材料的光学特性可以很容易地变化。因此，通过稍微改变材料成分， 这种光纤的波长可以被“调谐”，使其成为一种通用技术，广泛适用于从任何来源传输IR能量。根据POC的初步计算，所提出的设计将导致光纤的传输损耗比其他光纤报告的最低损耗低几个数量级，为10.6微米。正是在这个波长下，我们建议首先 展示这项技术。 ***
