Recent developments of the fixed gap, spherical mirror confocal Fabry-Perot interferometer for time resolved high resolution laser spectroscopy, including the measurement of spatial coherence, are described and illustrated with an interferogram of a pure single mode giant pulse ruby laser of 4 x 10(8) mW/cm(2)/sr brightness. Applications of a new multiple-beam image tube framing camera, producing up to ten consecutive frames on a nanosecond time scale, are discussed together with limitations arising from photocathode saturation in single stage image tube streaking and framing cameras. Properties of dye lasers, including spectral narrowing to a single longitudinal cavity mode and mode locking, are reported, and a simple coaxial linear pinch flashtube pumped dye laser system is described. A direct measurement of an optical frequency Stark shift of the 7699-A potassium resonance line has been obtained employing a ruby pumped dye laser as a background continuum source, and subpicosecond pulses from a Nd in glass relaxation oscillator have been measured.
介绍了用于时间分辨高分辨率激光光谱学的固定间隙球面镜共焦法布里-珀罗干涉仪的最新进展，包括空间相干性的测量，并用亮度为4×10⁸mW/cm²/sr的纯单模巨脉冲红宝石激光器的干涉图进行了说明。讨论了一种新型多束像管分幅相机的应用，该相机能在纳秒时间尺度上产生多达十幅连续图像，同时还讨论了单级像管扫描和分幅相机中光阴极饱和所带来的局限性。报告了染料激光器的特性，包括光谱窄化到单个纵向腔模和锁模，并描述了一种简单的同轴线性箍缩闪光灯泵浦染料激光系统。利用红宝石泵浦染料激光器作为背景连续光源，直接测量了7699埃钾共振线的光学频率斯塔克位移，并测量了玻璃中钕弛豫振荡器产生的亚皮秒脉冲。
