The most typical laser-Lively unusual earth ions and host media along with some standard emission wavelengths are revealed 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 �?usually single crystals (monocrystalline optical components) �?which can be utilised as get media for strong-condition lasers. In most cases, They can be doped with possibly trivalent unusual earth ions or transition metallic ions.

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。

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

A handful of laser crystal products are demonstrated where by some saturable absorber content is incorporated for passive Q switching of the laser.

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。

For quasi-3-amount laser gain media or perhaps 3-degree achieve media, a person often must limit the length to a value which can be way too small for successful pump absorption, as reabsorption consequences would if not spoil the performance. For side pumping, added things to consider appear into Enjoy; Moreover successful pump absorption, it is crucial to acquire an appropriate spatial shape from the acquire profile.

Diverse crystalline supplies are really diverse concerning their more info hardness together with other Houses, which figure out with which solutions And the way conveniently they can be Slice and polished with good quality.

For a variety of causes, composite crystals are getting to be well-known. These Have a very spatially various chemical composition and might be designed with Unique designs.

There exists a wide array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline constructions. 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。
