The commonest laser-active unusual earth ions and host media along with some typical emission wavelengths are proven in the next table:
These ions allow the crystal to amplify gentle with the laser wavelength through stimulated emission, when energy is equipped into the crystal through absorption of pump gentle (�?optical pumping
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。
Additionally, some versatility is lost in experiments if just one simply cannot try out absorbers with unique thickness or doping focus, as an example, without the need of exchanging the laser crystal by itself.
Which geometry, dopant and doping focus of your obtain medium are most useful depend on several elements. The obtainable pump source (type of laser diode or lamp) along with the envisaged pumping arrangement are crucial variables, but the material by itself also has some impact. As an example, titanium–sapphire lasers ought to be pumped with large intensities, for which the shape of a transversely cooled rod, operated with rather little pump and laser beam diameter, is a lot more appropriate than e.
GWU features all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a broad number of specifications. Apart from the well-founded supplies, modern crystals with exceptional Attributes like Yb:CALGO can open new horizons for demanding laser programs. Regardless of irrespective of whether personal parts for R & D applications are demanded or Price tag-productive numbers in smaller, medium or big batches with in-time delivery to the creation line are essential: GWU’s committed provider helps you to find the finest core factors more info to your 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。
g. a skinny disk. As A further example, Q-switched lasers attain a better populace density from the higher laser amount and they are therefore much more delicate to quenching outcomes and Electrical power transfer procedures; hence, a lessen doping density is commonly suitable for these products. For high-energy lasers, reduce doping densities are frequently used to limit the density of warmth technology, While slim-disk lasers get the job done ideal with hugely doped crystals. A lot of laser merchandise don't get to the comprehensive overall performance probable because such aspects haven't been appropriately worked out.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
People surfaces that happen to be passed from the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.

For several reasons, composite crystals are getting to be well-known. These Use a spatially different chemical composition and will be produced with Particular styles.
With That idea, one particular does not want a further saturable absorber crystal, making sure that one may perhaps make additional compact Q-switched laser setups with decreased interior parasitic losses. On the other hand, unwanted side effects can also take place, for example getting undesirable valence states of your associated ions or Strength transfers.
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。
