| 术语 | laser |
| 释义 | laser 激光器;［雷射］ 1. A device which transmits an extremely narrow and coherent beam of electromagnetic energy in the visible light spectrum. 一种能够发射可见光谱电磁能的极细的相干光束的装置。 2. In optoelectronics, a device that emits light rays which are in phase, travelling in the same direction and essentially of the same wavelength (the same frequency), i.e., colour. A laser beam does not diverge by a significant amount and maintains a high energy density. It thus can travel great distances without diverging from a tight beam. Lasers are used in optical signalling devices, high-speed printers, fiber optics and holography, etc. 在光电子学中,一种发射光线的器件,所发射的光线是同相的,沿同一方向传播,且其波长 (或说其频率)完全一样,亦即颜色完全一样。激光束不会明显发散,且能保持高的能量密度。 因此,它可以发射到很远的地方而不从密集的光束中发散。激光器应用于光通信设备、高速 打印机、光纤光学和全息照相术等。 3. In 3800 Printing Subsystem, a device that emits a beam of coherent light that forms the image on the photoconductor that is subsequently transferred to the paper. 在IBM 3800打印子系统中,一种发出相干光束的设备,发出的光束在光电导体上形成图象, 继而被传送到打印纸上。 Light Amplification by Stimulated Emission of Radiation的 缩写。 |
