激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。

A higher area good quality is obviously vital. Requirements of surface flatness in many cases are better than . This can help to prevent both equally scattering losses and wavefront distortions which might degrade the laser's beam high-quality. Furthermore, scratch and dig technical specs

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

Laser modeling and simulation can be used to reliably identify the ideal crystal dimensions, doping density And perhaps values of extra parameters.

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

For quasi-3-degree laser get media or simply a few-amount gain media, 1 usually should Restrict the size to a price and that is much too short for efficient pump absorption, as reabsorption effects would or else spoil the efficiency. For side pumping, extra factors come into play; In addition to efficient pump absorption, it is important to acquire an acceptable spatial form on the gain profile.

The medium must have a significant transparency (very low absorption and scattering) during the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this depends on the quality of the fabric, based on aspects of your fabrication system.

With that concept, just one will not need a further saturable absorber crystal, to ensure that a person could make extra read more compact Q-switched laser setups with decrease internal parasitic losses. On the other hand, unwanted Unintended effects can also manifest, including getting unwanted valence states on the associated ions or Vitality transfers.
