激光是六十年代新出现的一门技术。迄今为止它已被用于国防军事系统,许多科研部门和精密加工、精密测距、等离子体诊断、光通讯甚至医疗部门、建筑工程部门等等。总之,在最近的科学发明中象激光那样举世瞩目的东西是不多的。最初出现的是固体光激射器, 使用的工作物质是红宝石,1960年制成。接着利用氦氖混合气体的高频放电制成了第一台连续振荡的气体光激射器。此后光激射器的研究、发展和应用有了巨大的进展,现在已制成了比初期远为先进的激光装置。在科学领域中已形成了包含微波激射器,光激射器及其应用
Laser is a new technology in the 1960s. So far it has been used in defense military systems, many scientific research departments and precision machining, precision ranging, plasma diagnostics, optical communications and even medical, construction and engineering departments. In short, things that have caught the world's attention like lasers in recent scientific inventions are few. Originally appeared as a solid-state lasers, working material used was ruby, made in 1960. The first continuous-wave gas photo-lasers were then fabricated using high-frequency discharge from a He-Ne mixture. Since then, research, development and application of light lasers have made tremendous progress, and now it has been made into a much advanced laser device. In the field of science has been formed, including microwave lasers, light lasers and their applications
