The most typical laser-Lively uncommon earth ions and host media together with some usual emission wavelengths are shown 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。
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。

Which geometry, dopant and doping concentration with the obtain medium are most useful depend upon several things. The offered pump source (form of laser diode or lamp) and also the envisaged pumping arrangement are crucial elements, but the material alone also has some influence. One example is, titanium–sapphire lasers need to be pumped with substantial intensities, for which the shape of a transversely cooled rod, operated with reasonably compact pump and laser beam diameter, is more acceptable than e.
GWU features all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a broad range of requirements. Apart from the properly-founded supplies, impressive crystals with outstanding Qualities like Yb:CALGO can open up new horizons for demanding laser purposes. It does not matter regardless of whether more info person pieces for R & D reasons are demanded or Expense-efficient quantities in smaller, medium or substantial batches with in-time shipping and delivery with the output line are desired: GWU’s focused assistance really helps to find the best Main elements for your personal application.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
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 way more than simply a way to fix the laser-active ions at certain positions in Room. A number of properties of your host material are 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。

The medium must have a superior transparency (low absorption and scattering) within the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this will depend on the caliber of the fabric, determined by aspects with the fabrication course of action.
With That idea, one particular doesn't need yet another saturable absorber crystal, making sure that one particular might make more compact Q-switched laser setups with decreased inner parasitic losses. Nevertheless, undesired Unintended effects may take place, 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。
