The commonest laser-Energetic exceptional earth ions and host media together with some usual emission wavelengths are revealed in the subsequent table:
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 components) �?which happen to be made use of as get media for reliable-state lasers. Usually, These are doped with possibly trivalent exceptional earth ions or changeover metallic ions.

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and also the upper-condition life span.
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。
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 maximum attainable doping concentration can rely strongly over the host material and its fabrication technique.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-three-level laser obtain media and even 3-stage obtain media, one particular often ought to limit the duration to a worth that is too quick for efficient pump absorption, as reabsorption consequences would if not spoil the general performance. For side pumping, additional concerns occur into Enjoy; besides efficient pump absorption, it is crucial to acquire a suitable spatial condition with the acquire profile.
Distinct crystalline resources are certainly distinct regarding click here their hardness together with other properties, which figure out with which techniques And just how easily they are often cut and polished with top quality.
The medium must have a substantial transparency (reduced absorption and scattering) from the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this relies on the caliber of the material, determined by facts from the fabrication method.
With That idea, one particular won't will need yet another saturable absorber crystal, in order that a person might make much more compact Q-switched laser setups with reduced inner parasitic losses. However, unwelcome side effects may additionally come about, including obtaining undesired valence states in the associated ions or Vitality transfers.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
