Various crystalline products are certainly various relating to their hardness along with other Attributes, which figure out with which procedures and how very easily they may be cut and polished with top quality.
The medium ought to have a higher transparency (very low absorption and scattering) in the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this relies on the caliber of the fabric, based on aspects of your fabrication procedure.
The host crystal is way more than simply a method to repair the laser-Lively ions at certain positions in space. Several 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。
The utmost possible doping concentration can count strongly around the host substance and its fabrication technique.

GWU-Lasertechnik has more than thirty several years of expertise in distributing laser crystals. Choose GWU to gain from our broad know-how and in-field practical experience!
Moreover, some flexibility is missing in experiments if a single cannot Check out absorbers with various thickness or doping focus, for instance, without the need of 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：

It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in some strong mount which also acts as a heat sink. Larger crystals are often used for side pumping e.g. with significant-electric power diode bars.
The most common laser-Lively exceptional earth ions and host media together with some common emission wavelengths are revealed in the subsequent table:
A number click here of laser crystal materials are already shown exactly where some saturable absorber substance is incorporated for passive Q switching of a laser.
For many factors, composite crystals have gotten popular. These Have a very spatially different chemical composition and will be produced 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, one doesn't need to have a further saturable absorber crystal, to make sure that a person may perhaps make extra compact Q-switched laser setups with lessen interior parasitic losses. On the other hand, undesired Unintended effects may come about, for example acquiring unwanted valence states of the associated ions or Strength transfers.

Laser crystals are optical crystals �?ordinarily one crystals (monocrystalline optical materials) �?that are utilized as achieve media for stable-state lasers. In most cases, They're doped with possibly trivalent scarce earth ions or changeover steel ions.
