所要求的经费用于支付InGaAsP和AlGaAs半导体二极管激光器的物理和应用研究的业务费用。半导体二极管激光器的年销售额预计超过30亿美元。半导体二极管激光器用于光通信系统、CD播放机和DVD播放机。尽管激光的商业用途，仍有操作方面的设备不了解。这项研究计划的目的是为了帮助理解激光器的操作，例如可以实现的光谱带宽以及波长可以在该光谱带宽上切换的速度。将研究仪器在气体和液体检测、光学相干层析成像和距离测量方面的应用。这项工作的意义在于了解操作的物理原理，从而提供高素质的人员和技术，以促进对二极管激光器的理解和应用。

Funds are requested to cover the operating costs of research on the physics and applications of InGaAsP and AlGaAs semiconductor diode lasers.   Sales of semiconductor diode lasers are estimated to be greater than 3 billion dollars per year.  Semiconductor diode lasers are used in optical communication systems, CD players, and DVD players.  Despite the commercial use of the lasers, there are still aspects of the operation of devices that are not understood. It is the intent of this research program to contribute to an understanding of the operation of the lasers, such as the spectral bandwidth that can be achieved and how rapidly the wavelength can be switched over this spectral bandwidth.  Applications of devices to the detection of gases and liquids, optical coherence tomography, and measurement of distance will be investigated.   The significance of the work is in the understanding of the physics of operation that will result, in the provision of highly qualified personnel and techniques for advancement of understanding, and the applications for diode lasers.
