These tables consist of only the commonest host crystals; numerous Other folks exist, that are significantly less frequently used.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical supplies) �?which happen to be employed as get media for strong-condition lasers. Most often, They're doped with possibly trivalent rare earth ions or changeover metal ions.
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。
This is straightforward to do: just locate the lock icon before the URL from the deal with bar and drag that into the bookmark toolbar With all the mouse. Just in case you find the bookmark entry far too lengthy, you could ideal-click it to edit the textual content, e.g. utilizing "RP Enc" as an alternative to "RP Photonics Encyclopedia".
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。
Certainly, it is very desirable that a given crystal high quality is produced continuously, Even though different laser models can have another sensitivity to content parameters.
The most achievable doping focus can depend strongly to the host materials and its fabrication method.
The host crystal is a great deal more than just a method to repair the laser-active ions at selected positions in space. Several Attributes from the host materials are very important:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
These surfaces which might be passed from the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium ought to have a significant transparency (minimal absorption and scattering) in the wavelength areas of pump and Laser Crystal laser radiation, and great optical homogeneity. To some extent, this relies on the caliber of the fabric, determined by facts in the fabrication system.
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It might be preset in some strong mount which also acts as being a heat sink. Larger crystals are often employed for aspect pumping e.g. with large-electricity diode bars.
