Laser modeling and simulation can be utilized to reliably figure out the optimum crystal Proportions, doping density and possibly values of supplemental 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 crystal is a lot more than simply a way to repair the laser-Lively ions at certain positions in Room. Quite a few Attributes of the host material are essential:
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-stage laser obtain media and even three-amount get media, one particular usually has to limit the duration to a price which can be as well short for economical pump absorption, as reabsorption outcomes would in any other case spoil the overall performance. For facet pumping, added factors come into Enjoy; Apart from efficient pump absorption, it can be crucial to get an acceptable spatial form of the achieve profile.

A large damage threshold with regard to pulse fluence or peak intensity is often essential for top-Power 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：
Which geometry, dopant and doping concentration on the attain medium are most advantageous depend upon quite a few elements. The readily available pump resource (kind of laser diode or lamp) along with the envisaged pumping arrangement are crucial factors, but the material by itself also has some affect. One example is, titanium–sapphire lasers ought to be pumped with higher intensities, for which the form of a transversely cooled rod, operated with reasonably compact pump and laser beam diameter, is a lot more appropriate than e.
These tables consist of only the most typical host crystals; a lot of Some others exist, which might be a lot less commonly utilised.
In this article you could post queries and feedback. In terms of they get approved through the author, they can show up over this paragraph along with the writer’s solution. The creator will choose acceptance according to sure standards. Basically, The difficulty has to be of adequately broad desire.
A number of laser crystal supplies are demonstrated the place some saturable absorber material is integrated for passive Q switching of the laser.
Not surprisingly, it is very fascinating that a website presented crystal top quality is created consistently, Though unique laser designs can have a distinct 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 concept, just one won't need to have an extra saturable absorber crystal, so that just one may possibly make much more compact Q-switched laser setups with decrease interior parasitic losses. Nevertheless, undesired Negative effects could also occur, like obtaining undesirable valence states on the included ions or Electrical power transfers.

Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical materials) �?which are utilised as acquire media for good-condition lasers. Most often, They can be doped with both trivalent exceptional earth ions or transition steel ions.
