The most typical laser-Lively scarce earth ions and host media along with some common emission wavelengths are shown in the subsequent desk:

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。

Laser crystals are optical crystals �?generally one crystals (monocrystalline optical resources) �?that are applied as acquire media for stable-point out lasers. Usually, They're doped with both trivalent rare earth ions or transition metal ions.

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 from the gain medium are most advantageous depend on several factors. The available pump resource (style of laser diode or lamp) plus the envisaged pumping arrangement are very important aspects, but the material by itself also has some influence. For example, titanium–sapphire lasers have to be pumped with significant intensities, for which the form of a transversely cooled rod, operated with fairly compact pump and laser beam diameter, is much more appropriate than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

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。

g. a thin disk. As A different example, Q-switched lasers get to the next population density while in the higher laser degree and so are therefore a lot more delicate to quenching outcomes and energy transfer processes; consequently, a decrease doping density is frequently suitable for these units. For top-electricity lasers, lessen doping densities are sometimes used to limit the density of warmth technology, although skinny-disk lasers perform most effective with highly doped crystals. Quite a few laser products never reach the full efficiency prospective for the reason that this kind of details have not been appropriately worked out.

The host crystal is far more than just a method to fix the laser-Lively ions at sure positions in Area. Several Qualities of your host material 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。

Different crystalline elements are incredibly diverse concerning their hardness and other Houses, which establish with which procedures And just how very easily they can be Minimize and polished with top quality.

For a variety of motives, composite crystals have become well-liked. These have a spatially different chemical composition and might be created with Unique styles.

There is an array of crystalline media, which may be grouped according to special atomic constituents and crystalline buildings. Some vital teams 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。
