These tables incorporate only the most common host crystals; lots of Other people exist, which are less usually employed.
Below you can post queries and comments. As far as they get approved through the author, they are going to surface earlier mentioned this paragraph along with the creator’s reply. The author will choose acceptance determined by particular conditions. In essence, the issue has to be of adequately broad interest.
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。
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。
Which geometry, dopant and doping focus of the gain medium are most beneficial depend on several aspects. The offered pump supply (variety of laser diode or lamp) and also the envisaged pumping arrangement are essential variables, but the fabric alone also has some impact. One example is, titanium–sapphire lasers ought to be pumped with superior intensities, for which the form of a transversely cooled rod, operated with rather tiny pump and laser beam diameter, is more appropriate than e.
GWU delivers all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) using a wide a number of specs. Other than the nicely-proven materials, modern crystals with superb Qualities like Yb:CALGO can open new horizons for demanding laser programs. Irrespective of regardless of whether particular person items for R & D functions are demanded or click here Price-economical numbers in little, medium or big batches with in-time supply for the creation line are wanted: GWU’s dedicated service helps to discover the best core elements for your software.
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
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。
Some laser crystal components happen to be demonstrated wherever some saturable absorber substance is included for passive Q switching of a laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
For quasi-a few-stage laser gain media or maybe three-degree get media, one particular usually needs to Restrict the duration to a value which is far too brief for economical pump absorption, as reabsorption results would if not spoil the effectiveness. For aspect pumping, added issues appear into play; Other than productive pump absorption, it is vital to obtain an acceptable spatial condition on the attain profile.

The medium should have a high transparency (minimal absorption and scattering) in the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, based on aspects of your fabrication approach.
With That idea, a person will not require yet another saturable absorber crystal, making sure that a person may perhaps make much more compact Q-switched laser setups with lessen interior parasitic losses. Even so, unwelcome side effects could also take place, including acquiring undesirable valence states of your associated ions or Electricity 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。
