LASER在英语中的意思是什么？

激光

Laser

激光是通过基于受激发射的电磁辐射的光放大过程发光的装置。 术语“激光”起源于“通过受辐射辐射的光放大”的缩写。 激光与其他光源不同，因为它相干地发光。 空间一致性允许激光被聚焦到一个紧密的位置，使激光切割和光刻等应用成为可能。 空间相干性也允许激光束在很长的距离上保持狭窄，从而可以应用诸如激光指示器。 激光器也可以具有高的时间相干性，这允许它们具有非常窄的光谱，即它们仅发射单色光。 时间相干可用于产生与飞秒一样短的光脉冲。 激光器有很多重要的应用。 它们用于常见的消费类设备，如光盘驱动器，激光打印机和条码扫描器。 它们用于激光手术和各种皮肤治疗的药物，以及用于切割和焊接材料的工业。 它们用于军事和执法装置，用于标记目标和测量范围和速度。

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". A laser differs from other sources of light because it emits light coherently. Spatial coherence allows a laser to be focused to a tight spot, enabling applications like laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over long distances, enabling applications such as laser pointers. Lasers can also have high temporal coherence which allows them to have a very narrow spectrum, i.e., they only emit a single color of light. Temporal coherence can be used to produce pulses of light—as short as a femtosecond. Lasers have many important applications. They are used in common consumer devices such as Optical disk drives, laser printers, and barcode scanners. They are used in medicine for laser surgery and various skin treatments, and in industry for cutting and welding materials. They are used in military and law enforcement devices for marking targets and measuring range and speed.

在英语 词典里laser的定义

字典中激光的第一个定义是高强度光学，红外或紫外线辐射的来源，因为受到固体，液体或气体介质中的受激发射。 在发射过程中所涉及的光子都具有相同的能量和相位，使得激光束是单色和一致的，从而使其能够被聚焦。 其他激光的定义是任何类似的光源产生的任何电磁辐射，如红外或微波辐射束。 激光也是使用激光，特别是作为医疗的一部分。
