These tables incorporate only the commonest host crystals; several Many others exist, which can be a lot less frequently utilized.
These ions allow the crystal to amplify light at the laser wavelength by using stimulated emission, when Electrical power is supplied towards the crystal by means of absorption of pump light-weight (�?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。
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。
Which geometry, dopant and doping concentration on the obtain medium are most useful count on a number of things. The offered pump source (style of laser diode or lamp) and also the envisaged pumping arrangement are crucial aspects, but the fabric itself also has some affect. For example, titanium–sapphire lasers should be pumped with high intensities, for which the form of the transversely cooled rod, operated with relatively modest pump and laser beam diameter, is a lot more suitable than e.
GWU features all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a broad variety of specifications. In addition to the nicely-set up supplies, revolutionary crystals with excellent properties like Yb:CALGO can here open up new horizons for demanding laser programs. No matter no matter if personal items for R & D needs are expected or cost-productive numbers in small, medium or huge batches with in-time delivery for that manufacturing line are necessary: GWU’s devoted assistance helps you to discover the ideal Main factors for your software.
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。
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。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
