Acquisition of Alexandrite Laser for Nonlinear Optical Materials Research

提供资金用于购买用于非线性光学（NLO）材料研究的翠绿宝石激光器。岭大现正推行一项长远计划，大幅提升其激光/非线性光学研究实验室，以支援两个范畴的研究活动：（i）研究可用于光开关、光计算及光功率限制应用的高光折射非线性光学材料的三阶极化率特性;（2）对用于光谱可调谐固体激光器、被动Q开关和锁模器的γ辐照色心和杂质掺杂晶体的性质的研究。 目前可用的激光器限于某些固定的波长和时间脉冲形状。具有可变波长和时间脉冲宽度的激光源是本实验室进行非线性光学材料研究的必要条件。该仪器也是有用的，以加强教育的本科生和研究生谁参加实验室。

Funds are provided for the purchase an Alexandrite laser for nonlinear optical (NLO) materials research. The University is following a long-term plan to significantly upgrade its Laser/NLO Research Laboratory to support research activities in two areas (i) characterization of the third-order susceptibility of highly photorefractive NLO materials of interest for optical switching, optical computing, and optical power limiting applications; and (2) research into the properties Of gamma-irradiated color centers and impurity doped crystals of interest for spectrally tunable solid-state lasers, passive Q-switches, and mode-lockers. The currently available lasers are limited to certain fixed wavelengths and temporal pulse shapes. A laser source with a variable wavelength and temporal pulse width is a necessity for NLO materials research being performed in this laboratory. The instrument also is useful for enhancing the education of the undergraduate and graduates students who participate in the laboratory.
