The commonest laser-active exceptional earth ions and host media along with some common emission wavelengths are proven in the next table:
These ions allow the crystal to amplify mild on the laser wavelength through stimulated emission, when Strength is provided into the crystal by way of absorption of pump light (�?optical pumping
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
Additionally, some versatility is shed in experiments if 1 are not able to Check out absorbers with unique thickness or doping concentration, one example is, without the need of exchanging the laser crystal alone.
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：
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
A significant area high-quality is not surprisingly crucial. Specifications of area flatness are sometimes much better than . This helps in order to avoid both scattering losses and wavefront distortions which might degrade the laser's beam good quality. Additionally, scratch and dig 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。
A few laser crystal elements have already been shown the place some saturable absorber website materials is included for passive Q switching of a laser.
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
It is clear that unique purposes bring on quite diverse demands on laser obtain media. Because of this, a broad vary of various crystals are utilised, and producing the proper choice is important for setting up lasers with optimum performance.

The medium ought to have a higher transparency (minimal absorption and scattering) while in the wavelength areas of pump and laser radiation, and fantastic optical homogeneity. To some extent, this relies on the quality of the fabric, based on aspects of the fabrication process.
With That idea, one particular won't will need an extra saturable absorber crystal, so that just one may possibly make much more compact Q-switched laser setups with lessen inside parasitic losses. Nevertheless, unwelcome Unwanted effects might also manifest, including getting undesirable valence states of your concerned ions or Electrical power transfers.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
