Laser modeling and simulation can be used to reliably ascertain the ideal crystal dimensions, doping density And maybe values of more parameters.
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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the higher-condition life span.
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-three-degree laser attain media and even a few-amount obtain media, just one frequently ought to Restrict the duration to a worth which can be far too shorter for effective pump absorption, as reabsorption results would usually spoil the performance. For side pumping, added concerns arrive into Perform; Aside from successful pump absorption, it can be crucial to acquire an appropriate spatial form in the obtain profile.

Also, some flexibility is misplaced in experiments if just one simply cannot try out absorbers with various thickness or doping concentration, for example, without the need of exchanging the laser crystal alone.
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 from the attain medium are most useful depend upon many factors. The obtainable pump supply (type of laser diode or lamp) as well as the envisaged pumping arrangement are very important aspects, but the fabric alone also has some impact. For example, titanium–sapphire lasers must be pumped with superior intensities, for which the shape of the transversely cooled rod, operated with rather smaller pump and laser beam diameter, is a lot more correct than e.
It might be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be set in certain good mount which also functions to be a heat sink. Bigger crystals usually are used for facet pumping e.g. with high-ability diode bars.
The commonest laser-active unusual earth ions and host media along with some standard emission wavelengths are shown in the next table:
Those surfaces which can be handed via the laser beam are Usually either oriented at Brewster's angle or have an anti-reflection coating.
Certainly, it is vitally attractive that a provided crystal high-quality is manufactured continually, While distinct laser types might have a unique sensitivity to content parameters.
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 idea, a single will not need yet another saturable absorber crystal, so here that a person could make more compact Q-switched laser setups with decreased interior parasitic losses. Having said that, undesired Uncomfortable side effects might also arise, which include obtaining undesired valence states in the associated ions or energy transfers.
GWU provides all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) by using a broad range of specifications. Other than the very well-set up products, impressive crystals with excellent Homes like Yb:CALGO can open up new horizons for demanding laser programs. No matter irrespective of whether particular person pieces for R & D needs are required or cost-economical quantities in compact, medium or large batches with in-time delivery to the manufacturing line are needed: GWU’s focused provider really helps to find the best Main parts on your application.
It is clear that distinct applications result in quite distinctive requirements on laser acquire media. For that reason, a broad vary of various crystals are employed, and earning the best alternative is important for developing lasers with the best possible overall performance.
