Unique crystalline elements are certainly various relating to their hardness along with other Attributes, which figure out with which approaches and how very easily they are often Slash and polished with good quality.
The medium must have a significant transparency (minimal absorption and scattering) from the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this relies on the quality of the material, determined by specifics with the fabrication system.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the higher-point out 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-a few-stage laser achieve media and even three-amount attain media, just one generally should limit the duration to a worth that's also brief for efficient pump absorption, as reabsorption outcomes would normally spoil the efficiency. For side pumping, more issues come into Participate in; besides efficient pump absorption, it is crucial to obtain an acceptable spatial shape with the acquire profile.

In addition, some adaptability is dropped in experiments if 1 simply cannot try out absorbers with different thickness or doping focus, click here 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 comprise only the commonest host crystals; lots of Many others exist, which are less frequently utilized.
The commonest laser-Energetic scarce earth ions and host media along with some usual emission wavelengths are proven in the following table:
A couple of laser crystal resources happen to be demonstrated exactly where some saturable absorber materials is included for passive Q switching of the laser.
For different motives, composite crystals have become well known. These have a spatially various chemical composition and will be made with Exclusive shapes.
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, 1 isn't going to have to have yet another saturable absorber crystal, to ensure that one particular may possibly make extra compact Q-switched laser setups with reduced internal parasitic losses. Nonetheless, unwanted Negative effects can also happen, for instance getting undesired valence states on the associated ions or Strength transfers.
GWU presents all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) by using a wide range of specifications. Apart from the properly-founded elements, revolutionary crystals with remarkable Attributes like Yb:CALGO can open new horizons for demanding laser apps. No matter whether or not individual parts for R & D applications are required or cost-efficient quantities in compact, medium or significant batches with in-time delivery for the manufacturing line are essential: GWU’s focused assistance helps you to find the most effective core components for your application.
It is apparent that distinct programs bring on really distinct specifications on laser attain media. Due to this, a wide selection of various crystals are applied, and creating the appropriate option is important for setting up lasers with the best possible performance.
