Various crystalline materials are quite different regarding their hardness along with other Houses, which figure out with which procedures and how very easily they may be Reduce and polished with high quality.

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 considerably more than simply a method to repair the laser-Lively ions at sure positions in Area. Quite a few Homes on the host content are very important:

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-3-degree laser acquire media or even a few-stage achieve media, a single frequently needs to Restrict the size to a value which is much too quick for effective pump absorption, as reabsorption effects would if not spoil the functionality. For side pumping, additional things to consider arrive into play; Other than successful pump absorption, it is vital to obtain an appropriate spatial shape with the acquire profile.

g. a skinny disk. As An additional case in point, Q-switched lasers reach the next population density from the higher laser level and are thus far more delicate to quenching outcomes and Vitality transfer procedures; as a result, a lessen doping density is commonly suitable for these gadgets. For top-energy lasers, reduce doping densities are often utilized to limit the density of warmth era, Even though slender-disk lasers operate ideal with very doped crystals. Lots of laser merchandise don't get to the full effectiveness prospective simply because these particulars haven't been more info effectively worked out.

Also, some versatility is lost in experiments if just one are unable to Check out absorbers with distinct thickness or doping focus, as an example, without exchanging the laser crystal by 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：

These tables incorporate only the commonest host crystals; several Other people exist, which happen to be significantly less often applied.

Here it is possible to submit issues and remarks. In terms of they get approved from the writer, they'll surface previously mentioned this paragraph along with the author’s response. The author will settle on acceptance determined by specific standards. Fundamentally, The difficulty have to be of sufficiently broad interest.

A couple of laser crystal components are already demonstrated the place some saturable absorber product is incorporated for passive Q switching of the laser.

Not surprisingly, it is extremely attractive that a provided crystal high-quality is produced consistently, Whilst unique laser patterns might have another sensitivity to product 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, a single will not need an additional saturable absorber crystal, making sure that just one may well make extra compact Q-switched laser setups with decrease internal parasitic losses. Nonetheless, unwanted side effects might also arise, like getting undesired valence states of the concerned ions or Electricity transfers.

Laser crystals are optical crystals �?generally single crystals (monocrystalline optical products) �?which might be applied as achieve media for sound-point out lasers. Usually, These are doped with either trivalent exceptional earth ions or transition steel ions.
