Different crystalline resources are extremely different relating to their hardness and other properties, which establish with which techniques And the way quickly they may be Reduce and polished with high quality.
The medium ought to have a high transparency (lower absorption and scattering) while in the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this depends upon the standard of the material, determined by specifics of your fabrication procedure.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the upper-state life time.
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。
For quasi-a few-amount laser gain media or even three-amount acquire media, a single generally needs to Restrict the duration to a price which is far too limited for economical pump absorption, as reabsorption results would usually spoil the functionality. For aspect pumping, added criteria occur into Perform; Other than productive pump absorption, it can be crucial to acquire a suitable spatial condition of your achieve profile.

Furthermore, some versatility is dropped in experiments if a person can't try out absorbers with diverse thickness or doping focus, as an example, without exchanging the laser crystal itself.
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：
Which geometry, dopant and doping focus of the acquire medium are most beneficial depend on many aspects. The obtainable pump source (style of laser diode or lamp) along with the envisaged pumping arrangement are essential factors, but the material alone also has some impact. For instance, titanium–sapphire lasers must be pumped with significant intensities, for which the shape of the transversely cooled rod, operated with comparatively little pump and laser beam diameter, is more suitable than e.
These tables comprise only the most common host crystals; quite a few Other individuals exist, which might be a lot less frequently employed.
Here you could submit queries and feedback. So far as they get acknowledged through the creator, they can seem higher than this paragraph together with the writer’s respond to. The creator will decide on acceptance determined by sure conditions. Basically, The problem needs to be of adequately broad interest.
These surfaces which can be handed via the laser beam are Generally both oriented at Brewster's angle or have an anti-reflection coating.
For various causes, composite crystals have gotten popular. These have a spatially varying chemical composition and may be designed with special shapes.
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。
With that concept, a person won't have to have yet another saturable absorber crystal, so that a single could make extra compact Q-switched laser setups with lower inner parasitic losses. Nevertheless, undesired Unintended effects may additionally arise, for example acquiring unwelcome valence states on the involved ions or Vitality transfers.

Laser crystals are optical crystals �?normally solitary crystals (monocrystalline optical products) �?that are utilized as acquire media for sound-state lasers. In most cases, they are doped with possibly trivalent unusual earth ions or changeover metal ions.
