These tables consist of only the most typical host crystals; a lot of Other folks exist, which happen to be less usually used.
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 concentration from the acquire medium are most beneficial count on various aspects. The obtainable pump resource (form of laser diode or lamp) as well as the envisaged pumping arrangement are crucial factors, but the material alone also has some affect. By way of example, titanium–sapphire lasers need to be pumped with higher intensities, for which the shape of the transversely cooled rod, operated with reasonably modest pump and laser beam diameter, is more correct than e.

Certainly, it is vitally attractive that a specified crystal top quality is made persistently, While unique laser styles might have a distinct sensitivity to materials parameters.
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。
A couple of laser crystal supplies happen to be demonstrated exactly where some saturable absorber content is included for passive Q switching of more info the laser.
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。
It is obvious that distinctive applications result in really various specifications on laser obtain media. For that reason, a wide selection of different crystals are employed, and generating the best decision is essential for setting up lasers with optimum overall performance.
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 created the whole world’s major Ti∶sapphire crystal (Φ235 mm), which 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 sound-point out lasers. With the rise in pulse Electricity, peak electricity, and repetition level of solid-state lasers, laser crystals will establish towards greater measurements, increased crystal excellent, and controllable vital performance.
It might be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It may be mounted in a few reliable mount which also functions for a warmth sink. Larger sized crystals are often useful for aspect pumping e.g. with substantial-ability diode bars.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
