Tunable, Narrowband, Long Wave Infrared Light Source

9361987我们提出了一种基于光学参量振荡器/光学参量放大对(OPO/OPA)的3-12微米窄带光源的设计、构造和评价。利用激光泵浦的可调谐KTP OPO不仅为泵浦ZnGeP2OPO提供了一种新的方法，而且为调谐和表征它提供了另一种选择。我们将评估缩小ZnGeP2OPO的石灰宽度的方法。由于飞秒和皮秒的激光是可用的。该系统可以得到超快可调谐红外光源。拟议的第一阶段计划有望为长期寻求的3-12微米可调谐激光光源的制造提供技术基础。***

9361987 Caughey We propose the design, construction and evaluation of a 3-12 um narrowband light source based on an optical parametric oscillator/optical parametric amplifier pair (OPO/OPA), consisting of ZnGeP, crystals that are pumped by a tunable Kl P OPO. The tunable KTP OPO, which is itself pumped by a Nd:YAG laser, provides a novel method not only for pumping the ZnGeP2 OPO, but for providing an additional option for tuning and for characterizing it. Means for narrowing the limewidth of the ZnGeP2 OPO will be evaluated. Since femtosecond and picosecond Nd:YAG lasers are available. the proposed system can lead to an ultrafast tunable IR source. The proposed Phase I program is expected to provide the technical base for the manufacture of a long sought 3- 12 um tunable laser source. ***
