The commonest laser-Lively unusual earth ions and host media along with some common emission wavelengths are shown in the following 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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise the upper-point out life span.
GWU gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a wide a number of technical specs. In addition to the perfectly-recognized elements, progressive crystals with fantastic properties like Yb:CALGO can open up new horizons for demanding laser purposes. Irrespective of no matter if particular person items for R & D reasons are essential or Price tag-effective figures in modest, medium or substantial batches with in-time shipping for your output line are needed: GWU’s focused service really helps to discover the very best core elements for your personal application.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Laser modeling and simulation may be used to reliably identify the ideal crystal dimensions, doping density And maybe values of more parameters.

For quasi-three-degree laser attain media or perhaps a few-degree get media, one particular normally really should limit the size to a price that's way too short for economical pump absorption, as reabsorption consequences would normally spoil the efficiency. For aspect pumping, supplemental concerns appear into Enjoy; Other than efficient pump absorption, it is necessary to get an appropriate spatial form in the obtain 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。
For different good reasons, composite crystals are getting to be popular. These Have got a spatially different chemical composition and may be manufactured with Exclusive designs.
There may be a variety of crystalline media, which can be grouped in accordance to big get more info atomic constituents and crystalline structures. Some important groups of crystals are:
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。
