Which geometry, dopant and doping focus of the achieve medium are most beneficial rely on numerous variables. The offered pump resource (form of laser diode or lamp) along with the envisaged pumping arrangement are essential elements, but the fabric itself also has some influence. One example is, titanium–sapphire lasers should be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with relatively compact 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。
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 can be employed to reliably determine the the best possible crystal Proportions, doping density And perhaps values of extra 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。

In 2017, we produced the world’s premier Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with really extensive emission spectra drives the event of laser diode pumped ultrafast solid-condition lasers. With the increase in pulse Electricity, peak power, and repetition charge of reliable-point out lasers, laser crystals will establish towards greater measurements, increased crystal high-quality, and controllable key overall performance.
With that concept, a single will not want a further saturable absorber crystal, making sure that just one may possibly make far more compact Q-switched laser setups with reduced internal parasitic losses. However, unwelcome side effects could also arise, like getting undesirable 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。
