These tables have only the commonest host crystals; numerous others exist, which might be much less usually made use of.
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。
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the upper-point out lifetime.

A high surface good quality is of course essential. Specs of surface area flatness are sometimes a lot better than . This can help to stay away from both of those scattering losses and wavefront distortions which may degrade the laser's beam high quality. Furthermore, scratch and dig specs
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
The host crystal is much more than just a way to repair the laser-Energetic ions at certain positions in Area. Many Qualities in the host substance are crucial:
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。
It is obvious that diverse apps bring on pretty distinctive requirements on laser gain media. For that reason, a wide array of different crystals click here are utilized, and producing the ideal preference is important for constructing lasers with the best possible general performance.
Distinct crystalline materials are certainly various relating to their hardness along with other Homes, which figure out with which procedures And just how simply they may be Reduce and polished with high quality.
In 2017, we produced the whole world’s greatest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with incredibly huge emission spectra drives the development of laser diode pumped ultrafast good-state lasers. With the increase in pulse Strength, peak energy, and repetition charge of sound-condition lasers, laser crystals will produce to larger sizes, higher crystal high quality, and controllable crucial functionality.
It might be oriented for in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It might be fastened in some stable mount which also acts to be a warmth sink. Larger sized crystals are often useful for facet pumping e.g. with high-electric power diode bars.
