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。
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。

Which geometry, dopant and doping focus in the attain medium are most advantageous count on various components. The available pump source (kind of laser diode or lamp) and the envisaged pumping arrangement are essential components, but the material alone also has some influence. By way of example, titanium–sapphire lasers need to be pumped with significant intensities, for which the form of a transversely cooled rod, operated with somewhat little pump and laser beam diameter, is much more proper 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。
A large surface high quality is of course essential. Specifications of floor flatness are frequently better than . This helps to stay away from both equally scattering losses and wavefront distortions which often can degrade the laser's beam quality. Also, scratch and dig requirements
g. a skinny disk. As A further case in point, Q-switched lasers arrive at a greater population density inside the higher laser level and they are thus extra sensitive to quenching effects and energy transfer procedures; thus, a decrease check here doping density is usually suitable for these units. For high-ability lasers, lessen doping densities will often be utilized to limit the density of warmth generation, Despite the fact that skinny-disk lasers work finest with very doped crystals. Several laser products and solutions never get to the complete general performance likely simply because these facts haven't been adequately labored out.
Several laser crystal resources are shown the place some saturable absorber content is integrated for passive Q switching of a laser.
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。

Unique crystalline materials are certainly various about their hardness together with other Qualities, which identify with which strategies And the way easily they are often Lower and polished with top quality.
The medium must have a large transparency (reduced absorption and scattering) during the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this is determined by the quality of the material, determined by particulars from the fabrication approach.
Applying our promoting package, you could Exhibit your emblem, additional beneath your products description, and these will been found by many photonics gurus.
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。
