The most common laser-active uncommon earth ions and host media along with some typical emission wavelengths are revealed in the following table:
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 �?normally one crystals (monocrystalline optical supplies) �?which can be utilized as attain media for stable-condition lasers. Most often, They are really doped with both trivalent scarce earth ions or changeover metallic ions.
Additionally, some overall flexibility is shed in experiments if one simply cannot try out absorbers with diverse thickness or doping focus, one example is, without exchanging the laser crystal alone.
This is straightforward to complete: just discover the lock icon before the URL from the tackle bar and drag that on the bookmark toolbar While using the mouse. Just in case you locate the bookmark entry far too very long, you may appropriate-simply click it to edit the textual content, e.g. using "RP Enc" as opposed to "RP Photonics Encyclopedia".

Naturally, it is vitally attractive that a specified click here crystal high-quality is developed persistently, Despite the fact that unique laser layouts can have a different sensitivity to materials parameters.
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。
The host crystal is much more than just a way to fix the laser-active ions at specified positions in space. Quite a few Homes with the host product are very important:
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。
