发出激光

His system, known grandiosely as a 'large aperture scintillometer', consists of a laser on one side of a field, a telescope on the other, and a lot of clever computing to interpret what the telescope sees. What that computing is trying to measure is how much the laser beam twinkles as it passes across the field.

Kleissl的系统有一个响亮的名字："大眼睛闪烁仪"，它由以下几部分构成：农田某一边放置一个激光器，另一边有一个望远镜，然后通过大量电脑智能分析，以解析望远镜收集得来的数据：激光器发出的激光在穿过农田，到达望远镜之前闪烁的次数。

A two-photon photopolymerization reaction has been happened using DPVPA as initiator using a Datachroom-5000 laser at 600 nm.

在760 nm的飞秒脉冲激光激发下，DPVPA和PPVPA均发出较强的上转换荧光，荧光峰分别位于468和452 nm。

When pumped with 800 nm laser irradiation, 2 {4 [2 (4 dimethylamino phenyl vinyl] phenyl} ethylamino ethanol and 2 {4 [2 (4 diethylamino phenyl vinyl] phenyl} ethylamino ethanol show strong two photon induced blue fluorescence at 436 and 440 nm respectively, while DMANHAS and 4 nitro benzoic acid 2 {4 [2 (4 diethylamino phenyl vinyl] phenyl} ethylamino ethyl ester exhibit no fluorescence.

在800 nm的飞秒脉冲激光激发下，反式-4-(N-羟乙基-N'-乙基氨基)-4'-二苯乙烯和反式-4-(N-羟乙基-N'-乙基氨基)-4'-二苯乙烯均发出较强的蓝紫色上转换荧光，荧光峰分别位于436和440 nm，而DMANHAS和反式-4-[N-(乙氧基羰基-4-硝基苯基)-N'-乙基氨基]-4'-二苯乙烯没有荧光。

When pumped with 800 nm laser irradiation, chromophores BPODPA, BBPOPA, and TBPOA showed strong two-photon excited blue green fluorescence at 502, 515, and 518 nm, respectively. These multibranched chromophores showed large TPA cross-section.

在800nm波长的激光激发下，化合物BPODPA、BBPOPA和TBPOA在二氯甲烷溶液中发出很强的蓝绿色双光子上转换荧光，荧光峰分别位于502、515和518nm。

A flashing laser at one end fires digital on/off signals along the fiber.At about 120,000 miles a second-more than half the speel of light-they zip to the other end.

在玻璃纤维的一端，一个不停闪动的激光发生装置不断发出数字式闪断信号，这些信号以大约每秒12万英里的速度——超过了1/2光速——飞快地传输到另一端。

The majority of the fleet, sluggish and disoriented, slowly aligned into a coherent fighting force: plasma arced from a hundred ships, and laser fire weaved lacy patterns on the dark of space.

舰队里大部分军舰，行动迟缓不辨方向，慢慢排列成一个连贯的战斗队形：等离子电弧从上百艘飞船发出，黑暗的太空中激光炮火编织成花哨的图案。

Accompanying with the absorption of laser energy,the plasmas emits a powerful ultraviolet up to x ray radiation,and the re radiation has a more powerful coupling with the target.

该等离子体区域在吸收入射激光的同时，会发出很强的紫外以至x 光辐射，它们与靶材有着更强的耦合。
