Laser modeling and simulation can be utilized to reliably establish the optimum crystal Proportions, doping density And perhaps values of more parameters.
The medium ought to have a substantial transparency (reduced absorption and scattering) inside the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this is dependent upon the quality of the material, determined by aspects in the fabrication course of action.
The host crystal is way more than simply a way to fix the laser-Lively ions at certain positions in space. Numerous properties of the host material are crucial:
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。
The maximum probable doping focus can rely strongly around the host material and its fabrication method.
g. a skinny disk. As A different instance, Q-switched lasers reach the next populace density inside the higher laser level and they are thus a lot more delicate to quenching effects and Electricity transfer processes; thus, a reduce doping density is frequently suitable for these devices. For top-electrical power lasers, lessen doping densities are frequently utilized to Restrict the density of warmth technology, Even though skinny-disk lasers get the job done very best with hugely doped crystals. Numerous laser goods tend not to reach the complete overall performance probable mainly because these types of information have not been effectively worked out.

A superior damage threshold when it comes to pulse fluence or peak intensity may be crucial for high-Vitality amplifiers.
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：

These tables include only the most common host crystals; many Other individuals exist, that happen to be considerably less regularly made use of.
Here you could post queries and responses. So far as they get accepted because of the author, they'll appear above this paragraph along with the author’s response. The creator will settle on acceptance based upon particular requirements. Fundamentally, The difficulty needs to be of adequately wide interest.
Some laser crystal elements are already demonstrated the place some saturable absorber content is incorporated for passive Q switching of the laser.
For numerous motives, composite crystals are becoming popular. These have a spatially various chemical composition and may be made with Specific styles.
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, just one won't will need an additional saturable absorber crystal, to make sure that a single could make a lot more compact Q-switched laser setups with reduced internal parasitic losses. Having said that, unwanted Uncomfortable side effects could also come about, for instance getting undesired valence states in the involved ions or Electrical power transfers.
GWU features all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) using a wide selection of requirements. Other than the well-recognized materials, impressive crystals with remarkable properties like Yb:CALGO can open new horizons for demanding laser purposes. No matter whether or not personal items for R & D reasons are required or cost-effective figures in tiny, medium or huge batches with in-time shipping and delivery for your manufacturing line are more info essential: GWU’s committed company helps you to find the ideal core factors for your personal software.
It is clear that unique purposes cause really distinct specifications on laser attain media. For that reason, a wide array of various crystals are utilised, and building the correct preference is important for setting up lasers with the best possible functionality.
