REG: Acquisition of a Mode-Locked Nd: YAG Laser

康奈尔大学电气工程学院将根据这项NSF工程研究设备赠款购买一台NSF工程研究设备赠款，用于支持工程研究。该激光器将安装在一个中心电光实验室，并将用于以下研究项目：产生用于电光器件表征的超快脉冲；泵浦可调谐色心激光拍频发生器，用于电光器件的频率表征；基于KF和NaF中的类F+2缺陷，探索可能用于激光的新的色心缺陷；以及探索含过渡金属离子的晶体，如掺Cr3+和Ti3+的镁橄榄石、蓝宝石和其他可能的基质的激光。我们将利用扩散、薄膜生长和离子注入等方法，探索快速制造和评估用于激光的新型光学材料的可行性。所要求的1.6um的基波输出线将为大多数这样的系统提供泵浦光源。0.532微米的二次谐波将被用来探索固体中能量传递的光谱。

The School of Electrical Engineering at Cornell University will purchase a Nd:YAG laser under this NSF Engineering Research Equipment Grant which will be dedicated to support engineering research. The Nd:YAG laser will be installed in a central electro-optics laboratory, and will be used for the following research projects: ultrafast pulse generation for electro-optical device characterization; pumping a tunable color center laser beat frequency generator for frequency characterization of electro-optic devices; exploring new color center defects for possible lasing based on F+2 - like defects in KF and NaF; and exploring lasing in transition-metal-ion bearing crystals such as Cr3+ and Ti3+ doped Forsterite, sapphire, and other likely hosts. Using diffusion, thin-film growth, and ion-implantation, we will explore the feasibility of quickly making and evaluating new optical materials for lasing. The fundamental output line at 1.6 um of the requested Nd:YAG laser will provide the pump source for most of these systems. The second harmonic at 0.532 um will be used to explore the spectroscopy of energy transfer in solids.
