These tables comprise only the most typical host crystals; many Other folks exist, that happen to be considerably less commonly utilized.
These ions permit the crystal to amplify mild for the laser wavelength by using stimulated emission, when Electrical power is supplied to the crystal through absorption of pump light (�?optical pumping

In addition, some flexibility is dropped in experiments if 1 simply cannot try out absorbers with diverse thickness or doping focus, by way of example, with out exchanging the laser crystal by itself.
Which geometry, dopant and doping concentration of the achieve medium are most useful rely on many variables. The offered pump supply (kind of laser diode or lamp) as well as envisaged pumping arrangement are crucial things, but the material by itself also has some affect. By way of example, titanium–sapphire lasers have to be pumped with superior intensities, for which the shape of a transversely cooled rod, operated with fairly tiny pump and laser beam diameter, is more proper than e.
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。
Not surprisingly, it is very appealing that a presented crystal top quality is created consistently, Despite the fact that various laser models may have a special sensitivity to material parameters.
The most feasible doping focus can rely strongly to the host Laser Crystal materials and its fabrication method.
Laser modeling and simulation can be utilized to reliably determine the ideal crystal Proportions, doping density And perhaps values of extra parameters.

For quasi-three-stage laser achieve media or maybe a few-amount acquire media, one particular generally really should limit the length to a value which can be too brief for productive pump absorption, as reabsorption outcomes would in any other case spoil the effectiveness. For side pumping, additional concerns come into Enjoy; Other than efficient pump absorption, it is crucial to get an appropriate spatial condition in the gain profile.

For different factors, composite crystals are becoming popular. These Have got a spatially varying chemical composition and can be produced with Exclusive styles.
You can find a variety of crystalline media, which can be grouped in accordance to important atomic constituents and crystalline structures. Some important groups of crystals are:
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。
