提起“激光”,我们很容易将其与武器联系在一起:如“激光制导导弹”和以激光作为瞄准具的各种“激光枪”、“激光炮”,等等。然而,今天我们要介绍给大家的新式武器—激光乐器,却能“化干戈为玉帛”,创造出令人无限遐想的美妙神奇的声光世界。 激光乐器的概念 激光,是基于受激发射方法原理而产生的一种相干光辐射,这种光的最人特点是能够将光能量高度集中,光束和波长可以精确定位和调整。自1960年美国首次研制成功第一台激光器--红
When it comes to “lasers,” we can easily associate it with weapons: “laser-guided missiles” and various “laser guns”, “laser guns” and the like that use lasers as sights. However, today we are going to introduce the new type of weapon, the laser instrument, to all of you. However, we can “transform the war into the hell” and create a wonderful magical sound and light world with infinite reverie. The concept laser of laser instrument is a kind of coherent light radiation based on the principle of stimulated emission. The most characteristic of this kind of light is its high concentration of light energy, precise positioning and adjustment of light beam and wavelength. The first laser successfully developed in the United States since 1960 - red
