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 in the attain medium are most beneficial count on several elements. The offered pump source (variety of laser diode or lamp) and also the envisaged pumping arrangement are very important factors, but the fabric itself also has some impact. Such as, titanium–sapphire lasers should be pumped with high intensities, for which the form of a transversely cooled rod, operated with somewhat modest pump and laser beam diameter, is much more ideal than e.

GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) with a wide a number of requirements. Moreover the well-established supplies, revolutionary crystals with excellent Attributes like Yb:CALGO can open new horizons for demanding laser apps. No matter whether specific pieces for R & D needs are required or Price tag-economical figures in smaller, medium or big batches with in-time shipping and delivery to the production line are needed: GWU’s focused service helps you to locate the ideal core elements to your application.

Certainly, it is very fascinating that a specified crystal good quality is developed persistently, although different laser layouts might have a different sensitivity to material 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 considerably more than just a method to repair the laser-active ions at particular positions in Room. Numerous properties with the host materials are essential:

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。

It is apparent that various apps bring on very different prerequisites on laser gain media. This is why, a broad vary of various crystals are utilized, and producing the right preference is essential for setting up lasers with ideal functionality.

The medium ought to have a substantial transparency (small absorption and scattering) inside the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined by the quality of the material, based on information on the fabrication process.

There's a variety of crystalline media, which can be grouped in accordance to important atomic constituents and read more crystalline buildings. Some significant groups of crystals are:

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。
