Narrowband Broadly Tunable Solid State Laser Source

他们建议基于新出现的紫翠宝石激光技术，设计、建造、开发和表征一种新的窄带、宽可调、脉冲固态激光光源。目前高分辨率光谱、光化学研究和分析化学所需的类型的脉冲窄带可调谐激光光源基于染料激光技术，并且使用起来相对昂贵和笨重。拟建的信号源建成后，将在光谱纯度、脉冲持续时间多功能性、脉冲能量和可靠性方面提供新的能力。也许最重要的是，当基于受激拉曼散射(SRS)和二次和三次谐波产生的非线性转换方法增强时，可用于化学应用的通用光源将变得比以前的技术提供巨大的成本效益、可靠性和操作简单性。我们相信，这一来源将极大地增加研究人员进行实验而不是维护激光的时间，并将使多个激光实验比现在更容易和更多的实验室进行。

They propose to design, build, develop, and characterize a new narrowband, broadly tunable, pulsed, solid state laser source based on the newly emerging alexandrite laser technology. Present day pulsed narrowband tunable laser sources of the type required for high resolution spectroscopy, photochemical studies, and analytical chemistry are based on dye laser technology and are relatively expensive and cumbersome to use. The proposed source, when completed, will provide new capabilities in spectral purity, pulse duration versatility, pulse energy and reliability. Perhaps most importantly, when augmented by nonlinear conversion methods based on stimulated raman scattering (SRS) and second and third harmonic generation, a general light source useful for chemical applications will become available that provides enormous cost benefits, reliability and operating simplicity over previous technology. This source, we believe, will greatly improve the amount of time researchers can spend on performing experiments rather than maintaining lasers and will permit multi laser experiments to be performed vastly more easily and at many more laboratories than is possible today.
