Laser pumping - Wikipedia
Laser pumping is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms.
What is Laser Pumping? | Coherent
Laser pumping refers to introducing energy into a laser system to produce a population inversion, where there are more atoms or molecules in an excited state than in the ground state. This increases the probability of stimulated emission of light and enables lasing to occur.
什么是激光泵浦？ - LumiMetriC. Com
激光泵浦是指向激光器中的介质注入能量，以达到所谓的粒子数反转状态的过程。 这种状态对于激光光的产生至关重要。 简单来说，激光泵浦就像是给激光器“加油”，为其提供工作所需的能量。 激光泵浦的核心是原子或分子的能级概念。 当这些粒子吸收能量时，它们会跳跃到更高的能态，即所谓的激发态。 激光动作的关键是在这些激发态的粒子数量上超过低能态（基态）的粒子数量——这种状态被称为粒子数反转。 受激发射是接下来的关键步骤。 在这里，一个激发态的粒子遇到 …
什么是激光泵浦？ | Coherent高意
激光泵浦是指在激光器系统中引入能量以产生粒子数反转，即激发态原子或分子的数量超过基态原子或分子。 这提高了光受激发射的概率，从而产生激光。 根据激光器的类型，可以通过多种方法实现泵浦，包括光泵浦、电泵浦和化学泵浦。 无论使用哪种泵浦方法，实现激光作用的关键是在增益介质中产生粒子数反转。 这是因为激光作用是基于一种称为受激发射的过程。 这个过程是爱因斯坦首次描述的。 如果增益介质中的激发态原子或分子被传入的光子激发，发射出波长和相 …
Optical Pumping – pump light, laser crystal, optically pumped …
As the host medium (a laser crystal, glass or piece of ceramic) is electrically insulating, optical pumping is the only way to supply the laser-active ions (e.g. rare earth ions) with energy. See Figure 1 as an example. Semiconductor lasers are in most cases
Laser Pumping - an overview | ScienceDirect Topics
2012年7月8日 · Laser pumping refers to the process of transferring energy from concentrated solar radiations to a laser gain medium, such as an Nd: YAG rod, to excite electrons from a lower energy state to a higher energy state.
Section 2.1: Diode Pumped Lasers Overview - Columbia University
The process by which atoms are raised from lower level to upper level is called pumping. Diode pumped lasers are becoming more and more important in laser machining. Before we describe diode pumped lasers in detail, let’s first review the common pumping methods, so that we can appreciate the advantages of diode laser pumping.
光参量振荡器 - 维基百科，自由的百科全书
光参量振荡器 （英語： Optical Parametric Oscillator）是一个振荡在光学频率的 参量振荡器。 它将输入的频率为 的 激光 （所谓的 泵浦光 （英语：Laser pumping）），通过二阶 非线性光学 相互作用，转换成两个的频率较低的输出光（信号光 和闲频光 ），两个输出光的频率之和等于输入光频率： 。 由于历史的原因，两个输出光被称为「信号光」和「闲频光」，其输出波较高频率的「信号」。 一个特殊情况下的简并的光参量振荡器 ，恰好输出频率为的泵浦光的频率的一 …
Diode-Pumped Lasers: Performance, Reliability Enhance
There are a few basic methods for introducing diode laser pump light into a laser crystal — two of which are end and side pumping. In general, end-pumped lasers deliver high-quality output beams with state-of-the-art performance and stability at powers up to tens of watts, while side-pumped lasers sacrifice beam quality to offer raw power as ...
