These tables contain only the most typical host crystals; numerous Some others exist, that are a lot less frequently utilized.
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。
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。
Which geometry, dopant and doping focus of your gain medium are most advantageous rely on numerous elements. The accessible pump resource (variety of laser diode or lamp) plus the envisaged pumping arrangement are essential elements, but the fabric by itself also has some impact. By way of example, titanium–sapphire lasers ought to be pumped with large intensities, for which the shape of the transversely cooled rod, operated with rather smaller pump and laser beam diameter, is a lot more suitable than e.

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。
The host crystal is far more than just a means to fix the laser-Lively ions at sure positions in Room. A variety of Attributes of the host materials are essential:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

Various crystalline supplies are really unique about their hardness together with other Qualities, which ascertain with which strategies And just how conveniently they can be Lower and polished with high quality.
In 2017, we made the globe’s major Ti∶sapphire crystal (Φ235 mm), which get more info supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with extremely extensive emission spectra drives the event of laser diode pumped ultrafast solid-state lasers. With the increase in pulse Electricity, peak power, and repetition fee of strong-point out lasers, laser crystals will build toward larger sized sizes, bigger crystal quality, and controllable key performance.
It may be oriented for close to perpendicular incidence from the laser beam, or at Brewster's angle. It may be set in some strong mount which also acts as a warmth sink. Much larger crystals usually are useful for facet pumping e.g. with higher-power diode bars.
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。
