These tables include only the most typical host crystals; a lot of others exist, that happen to be less often utilized.
Listed here you can post thoughts and opinions. So far as they get acknowledged through the author, they'll appear earlier mentioned this paragraph together with the creator’s answer. The creator will choose acceptance according to sure standards. Basically, The difficulty has to be of sufficiently wide curiosity.
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。
On top of that, some versatility is dropped in experiments if one particular are unable to Check out absorbers with distinct thickness or doping concentration, for instance, without having exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the higher-state life time.
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 figure out the ideal crystal dimensions, doping density And perhaps values of added 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。
For quasi-3-amount laser achieve media or perhaps 3-amount obtain media, a person usually needs to limit the size to a worth that is way too short for check here effective pump absorption, as reabsorption outcomes would otherwise spoil the efficiency. For facet pumping, extra things to consider occur into play; Apart from successful pump absorption, it can be crucial to acquire an acceptable spatial condition of your attain profile.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
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 particularly large emission spectra drives the development of laser diode pumped ultrafast sound-condition lasers. With the rise in pulse Electrical power, peak energy, and repetition price of reliable-condition lasers, laser crystals will develop in the direction of greater measurements, larger crystal good quality, and controllable essential effectiveness.
It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be mounted in a few sound mount which also acts to be a warmth sink. Larger crystals are usually useful for aspect pumping e.g. with large-ability 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。
