The commonest laser-Lively uncommon earth ions and host media together with some regular emission wavelengths are revealed in the subsequent desk:
These ions permit the crystal to amplify mild in the laser wavelength through stimulated emission, when Electricity is provided towards the crystal via absorption of pump mild (�?optical pumping
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
On top of that, some overall flexibility is lost in experiments if one particular can't try out absorbers with distinct thickness or doping concentration, such as, without exchanging the laser crystal alone.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the upper-condition life time.
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。
Not surprisingly, it is extremely fascinating that a given crystal good quality is developed regularly, While various laser types might have a different sensitivity to substance 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。
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。

Diverse crystalline supplies are really diverse concerning their hardness together with other here Qualities, which identify with which strategies And exactly how very easily they may be Lower and polished with top quality.
GWU-Lasertechnik has in excess of thirty years of expertise in distributing laser crystals. Pick out GWU to take advantage of our huge knowledge and in-discipline working experience!
With That idea, one particular does not want an additional saturable absorber crystal, so that a person may possibly make a lot more compact Q-switched laser setups with lower interior parasitic losses. Even so, unwanted side effects may take place, such as acquiring unwanted valence states with the 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。
