These tables contain only the commonest host crystals; numerous Other folks exist, that are significantly less commonly applied.

These ions empower the crystal to amplify gentle at the laser wavelength by using stimulated emission, when Strength is supplied into the crystal by using absorption of pump mild (�?optical pumping

激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

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。

Which geometry, dopant and doping concentration of the attain medium are most advantageous depend upon numerous elements. The accessible pump source (type of laser diode or lamp) as well as envisaged pumping arrangement are very important factors, but the fabric itself also has some impact. One example is, titanium–sapphire lasers must be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with relatively smaller pump and laser beam diameter, is much more appropriate 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's very attractive that a supplied crystal high-quality is produced continuously, Whilst distinctive laser types can have another sensitivity to content parameters.

The most doable doping concentration can more info rely strongly around the host substance and its fabrication approach.

Laser modeling and simulation can be utilized to reliably identify the ideal crystal Proportions, doping density and possibly values of more parameters.

激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

For quasi-a few-stage laser achieve media or maybe 3-stage attain media, a single generally really should Restrict the length to a value which happens to be too quick for efficient pump absorption, as reabsorption outcomes would in any other case spoil the general performance. For aspect pumping, more concerns appear into Enjoy; Other than effective pump absorption, it can be crucial to obtain a suitable spatial form with the gain profile.

Distinct crystalline supplies are really diverse about their hardness and also other properties, which establish with which methods And exactly how very easily they are often cut and polished with good quality.

For a variety of explanations, composite crystals have gotten common. These Have a very spatially various chemical composition and might be designed with Specific shapes.

You can find a wide range of crystalline media, which can be grouped according to special atomic constituents and crystalline constructions. Some significant teams of crystals are:
