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 �?commonly one crystals (monocrystalline optical supplies) �?which might be used as obtain media for reliable-point out lasers. Most often, They can be doped with possibly trivalent unusual earth ions or transition metal 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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
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。
A substantial surface area excellent is obviously critical. Requirements of area flatness are frequently a lot better than . This can help to prevent the two scattering losses and wavefront distortions which could degrade the laser's beam excellent. On top of that, scratch and dig technical 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。
Laser modeling and simulation can be utilized to reliably identify the ideal crystal Proportions, doping density and possibly values of supplemental parameters.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

In 2017, we formulated the planet’s most significant Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with exceptionally broad emission spectra drives the development of laser diode pumped ultrafast good-state lasers. With the increase in pulse Strength, peak ability, and repetition price of sound-condition lasers, laser crystals will acquire toward much larger dimensions, bigger crystal high quality, and controllable crucial functionality.
With that concept, a single isn't going to need to have a further saturable absorber crystal, to ensure one particular may possibly make a lot more compact Q-switched laser setups with reduced internal parasitic losses. However, undesired Unintended effects may additionally take place, such as acquiring unwanted valence states with the concerned ions or Electrical power transfers.
