Laser crystals are optical crystals �?normally solitary crystals (monocrystalline optical materials) �?which might be used as achieve media for good-point out lasers. Generally, They can be doped with possibly trivalent scarce earth ions or changeover 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：
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。
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
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 may be used to reliably determine the optimum crystal dimensions, doping density And maybe 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。
It is obvious that various apps lead to very different needs on laser attain media. Due to this, a wide array of various crystals are utilised, and making the ideal decision is essential for setting up lasers with ideal functionality.

In 2017, we produced the planet’s greatest Ti∶sapphire crystal (Φ235 mm), more info which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with incredibly large emission spectra drives the development of laser diode pumped ultrafast stable-state lasers. With the rise in pulse Electricity, peak energy, and repetition amount of solid-condition lasers, laser crystals will acquire towards more substantial dimensions, higher crystal top quality, and controllable vital functionality.
With That idea, 1 does not want an extra saturable absorber crystal, to ensure one particular may possibly make far more compact Q-switched laser setups with decrease inner parasitic losses. Even so, undesirable Negative effects may additionally arise, for example acquiring unwanted valence states of your concerned ions or energy transfers.
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。
