Laser modeling and simulation can be utilized to reliably identify the ideal crystal Proportions, doping density and possibly values of additional 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 medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the higher-point out life time.

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 a few-stage obtain media, 1 often ought to limit the length to a worth which can be as well shorter for successful pump absorption, as reabsorption results would otherwise spoil the effectiveness. For side pumping, supplemental issues come into Enjoy; Apart from efficient pump absorption, it is crucial to obtain an appropriate spatial shape on the acquire profile.

GWU-Lasertechnik has much more than thirty yrs of knowledge in distributing laser crystals. Pick GWU to take advantage of our wide awareness and in-field working experience!

A high problems threshold when it comes to pulse fluence or peak depth may here be important for prime-energy 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 focus of your acquire medium are most beneficial count on a number of variables. The out there pump source (kind of laser diode or lamp) as well as envisaged pumping arrangement are important elements, but the material by itself also has some affect. Such as, titanium–sapphire lasers must be pumped with large intensities, for which the shape of a transversely cooled rod, operated with somewhat small pump and laser beam diameter, is much more correct than e.

It could be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It could be set in certain solid mount which also functions as being a heat sink. Larger crystals are frequently useful for side pumping e.g. with large-electricity diode bars.

The commonest laser-Lively exceptional earth ions and host media along with some usual emission wavelengths are shown in the next table:

A handful of laser crystal elements have been demonstrated the place some saturable absorber material is integrated for passive Q switching of the laser.

For many factors, composite crystals have gotten well-liked. These Have got a spatially varying chemical composition and will be designed 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 won't need to have a further saturable absorber crystal, to ensure that a person could make extra compact Q-switched laser setups with reduced inside parasitic losses. Nevertheless, unwanted side effects may happen, for example acquiring unwelcome valence states in the associated ions or Electrical power transfers.

Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical components) �?that happen to be made use of as attain media for stable-condition lasers. Typically, These are doped with either trivalent rare earth ions or transition steel ions.
