These tables comprise only the most common host crystals; numerous Some others exist, which might be less commonly made use of.

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。

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。

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 concentration with the attain medium are most advantageous rely on many things. The accessible pump source (sort of laser diode or lamp) along with the envisaged pumping arrangement are very important things, but the fabric by itself also has some affect. By way of example, titanium–sapphire lasers must be pumped with significant intensities, for which the shape of the transversely cooled rod, operated with rather modest pump and laser beam diameter, is much more proper than e.

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。

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。

The utmost attainable doping concentration can rely strongly around the host more info content and its fabrication system.

Laser modeling and simulation can be employed to reliably figure out the ideal crystal Proportions, doping density And perhaps values of more parameters.

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 various motives, composite crystals have become common. These Have a very spatially various chemical composition and might be designed with Exclusive designs.

There is a wide array of crystalline media, which can be grouped according to big atomic constituents and crystalline structures. 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。
