9461060谢克特非线性光学材料正被用于越来越广泛的应用。随着用于光通信、光信息处理和集成光学的光学元件尺寸的减小，必须找到开发微型非线性元件的方法。本程序研究了BetaBaB204在纤维形式下的生长。Lasergenics公司获得了斯坦福大学拥有的激光加热基座生长技术的专利许可，该技术用于生长这种新的和有趣的非线性材料的单晶光纤。这种材料特别适用于半导体二极管激光器和NdYAG光的倍频输出。这项研究将研究成分、温度、压力、气氛和拉速对纤维生长的影响。得到的纤维将进行成分、光学质量和均匀性测试。将进行二次谐波产生的初步测试。预计第二阶段将优化这种材料的生长，并建立二次谐波装置和倍频激光二极管阵列。还将探索一种基于掺钛蓝宝石光纤的可调谐光纤激光器系统。

9461060 Schecht Nonlinear optical materials are being used for an ever widening array of applications. As optical elements for optical communications, optical information processing and integrated optics decrease in size, ways must be found to develop nonlinear elements of miniature size as well. This program investigates the growth of BetaBaB204 in fiber form. Lasergenics Corporation has license to the patents held by Stanford University to the laser-heated pedestal-growth technique that is used in the growth of single crystal fibers of this new and interesting nonlinear material. This material is particularly interesting for frequency doubling the output of semiconductor diode lasers and the Nd:YAG laser. The research will investigate the effects of composition, temperature, pressure, atmosphere and pull-rate on fiber growth. Resulting fibers will be tested for composition, optical quality, and uniformity. Initial tests for second harmonic generation will be done. Phase II is expected to optimize the growth of this material and to build second harmonic devices and frequency-double laser diode arrays. A tunable fiber laser system based on fibers of titanium doped sapphire will also be explored.
