These tables comprise only the most typical host crystals; lots of Other individuals exist, which are significantly less commonly 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。
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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 on the attain medium are most advantageous depend upon numerous variables. The offered pump resource (kind of laser diode or lamp) as well as the envisaged pumping arrangement are important elements, but the fabric itself also has some affect. As an example, titanium–sapphire lasers must be pumped with significant intensities, for which the form of the transversely cooled rod, operated with fairly modest pump and laser beam diameter, is more suitable than e.
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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a thin disk. As another example, Q-switched lasers reach a greater inhabitants density inside the higher laser stage and so are thus much more delicate to quenching results and energy transfer procedures; consequently, a reduced doping density is frequently suitable for these products. For prime-ability lasers, lower doping densities are often utilized to limit the density of warmth generation, While slender-disk lasers perform ideal with very doped crystals. Several laser products and solutions tend not to get to the entire functionality opportunity simply because these details haven't been thoroughly worked out.
Laser modeling and simulation can be utilized to reliably ascertain the optimum crystal dimensions, doping density And perhaps values of added 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。

Different crystalline elements are quite various about their hardness along with other properties, which identify with which approaches and how very easily they may be Reduce and polished with high quality.
GWU-Lasertechnik has over thirty years of expertise in distributing laser crystals. Opt for GWU to take advantage of our huge knowledge and in-subject working experience!
There is an array of crystalline media, which can be grouped according to big atomic constituents and crystalline constructions. Some vital teams of crystals are:
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。
