The commonest laser-Energetic unusual earth ions and host media along with some normal emission wavelengths are proven in the following desk:
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 �?ordinarily single crystals (monocrystalline optical products) �?that happen to be made use of as obtain media for solid-condition lasers. Most often, They may be doped with both trivalent scarce earth ions or transition steel ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and also the upper-point out lifetime.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
Obviously, it is extremely fascinating that a provided crystal top quality is made regularly, although distinctive laser models can have a different sensitivity to substance parameters.
The maximum doable doping concentration can rely strongly on the host product and its fabrication strategy.
The host crystal is a great deal more than just a means to fix the laser-Lively ions at particular positions in House. A number of Houses in the host material are 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。
It is clear that unique apps bring on incredibly unique necessities on laser get media. Due to this, a wide vary of various crystals are made use of, and earning the ideal alternative is important for constructing lasers with the best possible general performance.
Various crystalline products are quite various relating to their hardness as well as other Attributes, which decide with which solutions And just how effortlessly they are often Slash and polished with good quality.
The medium ought to have a substantial transparency (minimal absorption and scattering) in the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this depends on the caliber of the fabric, determined by aspects in the fabrication process.
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be fastened in certain stable click here mount which also functions for a warmth sink. Larger crystals are often used for facet pumping e.g. with superior-ability diode bars.
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。
