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。
This is a snap to carry out: just discover the lock icon in front of the URL from the deal with bar and drag that into the bookmark toolbar With all the mouse. Just in case you locate the bookmark entry also lengthy, it is possible to ideal-click it to edit the text, e.g. utilizing "RP Enc" instead of "RP Photonics Encyclopedia".
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
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 An additional example, Q-switched lasers attain an increased population density while in the upper laser amount and therefore are as a result a lot more delicate to quenching effects and Strength transfer processes; for that reason, a lessen doping density is frequently appropriate for these equipment. For prime-energy lasers, decrease doping densities are sometimes accustomed to limit the density of heat generation, Whilst slim-disk lasers work ideal with extremely doped crystals. Numerous laser items tend not to reach the whole overall performance opportunity since these facts have not been effectively labored out.
Laser modeling and simulation may be used to reliably ascertain the optimum 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。
It is clear that various apps bring on very various more info specifications on laser obtain media. Because of this, a broad selection of different crystals are made use of, and generating the right choice is essential for developing lasers with optimum performance.

In 2017, we created the globe’s biggest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with really huge emission spectra drives the development of laser diode pumped ultrafast good-condition lasers. With the increase in pulse Electrical power, peak electrical power, and repetition price of good-state lasers, laser crystals will acquire in direction of larger measurements, higher crystal high-quality, and controllable key general performance.
With that concept, just one isn't going to will need yet another saturable absorber crystal, to ensure one may make additional compact Q-switched laser setups with reduced internal parasitic losses. On the other hand, unwelcome Unwanted side effects may additionally manifest, including acquiring undesired valence states on the concerned ions or Electricity transfers.
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。
