The most common laser-Energetic exceptional earth ions and host media along with some common emission wavelengths are revealed in the next 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 solitary crystals (monocrystalline optical supplies) �?which happen to be employed as attain media for sound-point out lasers. Generally, These are doped with possibly trivalent unusual earth ions or changeover metallic 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。

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

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。

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 number of laser crystal resources have been demonstrated where by some saturable absorber materials is integrated 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。

It is apparent that various programs bring click here about quite diverse necessities on laser get media. Due to this, a wide selection of different crystals are employed, and creating the proper choice is important for setting up lasers with optimum performance.

Different crystalline products are really diverse relating to their hardness and various Attributes, which determine with which procedures And exactly how easily they are often Reduce and polished with top quality.

GWU-Lasertechnik has a lot more than 30 a long time of practical experience in distributing laser crystals. Select GWU to reap the benefits of our broad understanding and in-discipline experience!

There exists a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some significant 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。
