These tables consist of only the most common host crystals; quite a few Other people exist, which happen to be much less routinely employed.

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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the higher-point out lifetime.
GWU provides all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) that has a broad a number of requirements. Aside from the very well-set up elements, revolutionary crystals with fantastic Qualities like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of no matter whether unique items for R & D needs are necessary or Charge-productive numbers in tiny, medium or significant batches with in-time shipping and delivery with the manufacturing line are wanted: GWU’s dedicated support really helps to find the best core components for the software.
Naturally, it is vitally desirable that a presented crystal high-quality is made continually, Whilst different laser models may have a special sensitivity to substance parameters.
g. a skinny disk. As another case in point, Q-switched lasers achieve a higher populace density within the upper laser stage and they are for that reason more delicate to quenching effects and Vitality transfer processes; therefore, a decrease doping density is commonly appropriate for these units. For top-electrical power lasers, lessen doping densities are sometimes utilized to Restrict the density of warmth technology, Even though slim-disk lasers perform most effective with extremely doped crystals. Several laser goods don't get to the complete overall performance opportunity simply because this kind of facts haven't been thoroughly worked out.
Laser modeling and simulation can be employed to reliably decide the ideal crystal dimensions, doping density And perhaps values of more 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-a few-stage laser acquire media or perhaps 3-amount gain media, just one typically ought to Restrict the duration to a price that's too shorter for productive pump absorption, as reabsorption effects would normally spoil the performance. For facet pumping, further criteria come into Participate in; Moreover effective pump absorption, it is vital to obtain an appropriate spatial condition on 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。
GWU-Lasertechnik has a lot more than 30 yrs of encounter in distributing laser crystals. Pick out GWU to reap the benefits of our wide know-how As well as in-discipline knowledge!
With That idea, just one isn't going to have to have a further saturable absorber crystal, so that a single could make additional compact Q-switched laser setups with lower interior parasitic losses. Nonetheless, undesirable side website effects may also take place, which include obtaining undesired valence states of the concerned ions or Power transfers.
