The most typical laser-Energetic uncommon earth ions and host media along with some usual emission wavelengths are demonstrated in the subsequent table:
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。
Which geometry, dopant and doping focus of your obtain medium are most useful rely upon many factors. The obtainable pump supply (style of laser diode or lamp) and the envisaged pumping arrangement are essential things, but the material itself also has some influence. By way of example, titanium–sapphire lasers ought to be pumped with substantial intensities, for which the shape of a transversely cooled rod, operated with fairly compact pump and laser beam diameter, is much more ideal 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。
g. a skinny disk. As Yet another case in point, Q-switched lasers achieve the next populace density during the upper laser degree and so are therefore a lot more sensitive to quenching results and energy transfer processes; thus, a lower doping density is often appropriate for these units. For prime-power lasers, lessen doping densities are often utilized to Restrict the density of warmth era, Though thin-disk lasers work best with highly doped crystals. Lots of laser products and solutions do not get to the entire functionality Laser Crystal prospective simply because such facts have not been thoroughly worked out.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
Those people surfaces which are handed by the laser beam are normally possibly oriented at Brewster's angle or have an anti-reflection coating.

In 2017, we developed the globe’s major 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 really large emission spectra drives the event of laser diode pumped ultrafast good-point out lasers. With the rise in pulse Strength, peak energy, and repetition price of reliable-point out lasers, laser crystals will acquire to bigger sizes, higher crystal top quality, and controllable crucial effectiveness.
It could be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be mounted in some strong mount which also functions for a heat sink. Greater crystals are generally used for facet pumping e.g. with substantial-electrical power diode bars.
