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。
This is a snap to accomplish: just locate the lock icon before the URL inside the handle bar and drag that towards the bookmark toolbar Along with the mouse. In case you discover the bookmark entry too prolonged, you could correct-click on it to edit the text, e.g. working with "RP Enc" instead of "RP Photonics Encyclopedia".
GWU features all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) having a broad variety of specifications. Besides the well-proven resources, modern crystals with exceptional Qualities like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of regardless of whether specific pieces for R & D applications are essential or Price-economical figures in compact, medium or massive batches with in-time delivery with the creation line are needed: GWU’s devoted company helps to discover the best core elements for your personal application.
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 One more case in point, Q-switched lasers get to the next population more info density from the higher laser level and therefore are thus more delicate to quenching consequences and Power transfer processes; thus, a lessen doping density is often appropriate for these gadgets. For high-electrical power lasers, decrease doping densities in many cases are used to Restrict the density of warmth era, While slender-disk lasers get the job done finest with highly doped crystals. Numerous laser products and solutions don't get to the total effectiveness likely since this sort of specifics have not been effectively labored out.
Several laser crystal products have already been shown wherever some saturable absorber product is incorporated for passive Q switching of 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。

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。
GWU-Lasertechnik has much more than thirty decades of experience in distributing laser crystals. Choose GWU to take advantage of our vast information and in-field experience!
With that concept, a single will not want an extra saturable absorber crystal, to ensure that 1 may make extra compact Q-switched laser setups with decrease inner parasitic losses. However, unwelcome Unintended effects may additionally happen, which include acquiring unwelcome valence states in the associated ions or Vitality 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。
