Laser modeling and simulation may be used to reliably determine the optimum crystal Proportions, doping density And perhaps values of extra parameters.
The medium ought to have a superior transparency (small absorption and scattering) inside the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this depends on the standard of the material, determined by information in the fabrication procedure.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as 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-three-amount laser obtain media as well as 3-level attain media, one particular generally really should Restrict the size to a price that is as well short for effective pump absorption, as reabsorption results would if not spoil the functionality. For side pumping, supplemental factors appear into Participate in; Other than successful pump absorption, it is important to get a suitable spatial condition in the acquire profile.

Additionally, some versatility is shed in experiments if one simply cannot try out absorbers with distinctive thickness or doping focus, for example, with no exchanging the laser crystal alone.
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 focus from the acquire medium are most useful depend on several elements. The out there pump source (form of laser diode or lamp) as well as the envisaged pumping arrangement are crucial variables, but the fabric by itself also has some affect. Such as, titanium–sapphire lasers need to be pumped with large intensities, for which the form of the transversely cooled rod, operated with comparatively compact pump and laser beam diameter, is a lot more proper than e.
These tables incorporate only the most common host crystals; numerous others exist, that happen to be significantly less regularly utilized.
The most common laser-Lively exceptional earth ions and host media along with some usual emission wavelengths are demonstrated in the following table:
Some laser crystal supplies are shown the place some saturable absorber product is included for passive Q switching of the laser.
Obviously, it is extremely desirable that a given crystal quality is manufactured continuously, While unique laser patterns can have a unique sensitivity to content parameters.
There is a wide array of crystalline media, which can be grouped according to big atomic constituents and crystalline structures. Some vital teams of crystals are:
With That idea, one does not need to have yet another saturable absorber crystal, to ensure that just one may perhaps make more compact Q-switched laser setups with reduced inside parasitic losses. On the other hand, unwelcome Unwanted side effects can also come about, for instance acquiring unwanted valence states of your involved ions or energy transfers.
GWU offers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) having a wide a number of specs. In addition to the properly-set up products, ground breaking here crystals with superb Houses like Yb:CALGO can open up new horizons for demanding laser programs. Regardless of whether person parts for R & D reasons are required or Price-efficient numbers in compact, medium or massive batches with in-time shipping for your generation line are desired: GWU’s dedicated company really helps to find the most effective core elements in your application.
It is clear that various applications produce extremely different prerequisites on laser attain media. This is why, a broad vary of different crystals are utilized, and creating the ideal alternative is essential for setting up lasers with ideal performance.
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。
