The most common laser-Lively uncommon earth ions and host media together with some typical emission wavelengths are proven in the next desk:
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?commonly one crystals (monocrystalline optical elements) �?which can be utilized as obtain media for stable-state lasers. In most cases, They may be doped with either trivalent exceptional earth ions or changeover metallic ions.
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。
This is straightforward to do: just discover the lock icon before the URL in the deal with bar and drag that into the bookmark toolbar With all the mouse. In the event you locate the bookmark entry too extended, you may suitable-click it to edit the textual content, e.g. using "RP Enc" as opposed to "RP Photonics Encyclopedia".
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。
Obviously, it is extremely desirable that a given crystal high-quality is generated continually, Despite the fact that distinct laser designs may have a special sensitivity to product parameters.
The maximum probable doping concentration can rely strongly on the host substance and its fabrication technique.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
These surfaces that are handed through the laser beam are Typically either oriented at Brewster's angle or have an anti-reflection coating.
