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。
Which geometry, dopant and doping concentration in the achieve medium are most useful rely on a number of components. The out there pump source (variety of laser diode or lamp) and the envisaged pumping arrangement are crucial elements, but the fabric itself also has some impact. For instance, titanium–sapphire lasers ought to be pumped with high intensities, for which the form of a transversely cooled rod, operated with reasonably modest pump and laser beam diameter, is a lot more suitable than e.
GWU features all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) with a broad assortment of technical specs. Besides the well-proven supplies, innovative crystals with remarkable properties like Yb:CALGO can open up new horizons for demanding laser applications. Despite regardless of whether person pieces for R & D uses are expected or cost-economical quantities in smaller, medium or huge batches with in-time shipping and delivery for that output line are desired: GWU’s devoted assistance helps to find the ideal Main factors for the application.
A significant area excellent is naturally essential. Technical specs of surface area flatness in more info many cases are better than . This allows to stay away from each scattering losses and wavefront distortions which often can degrade the laser's beam quality. Additionally, scratch and dig requirements
The most achievable doping concentration can depend strongly about the host content and its fabrication strategy.
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。
For quasi-three-degree laser achieve media as well as 3-amount acquire media, just one typically has to Restrict the duration to a value which can be as well brief for productive pump absorption, as reabsorption effects would or else spoil the functionality. For aspect pumping, further considerations appear into Engage in; Aside from successful pump absorption, it is crucial to get an appropriate spatial form in the gain 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 a long time of expertise in distributing laser crystals. Decide on GWU to take pleasure in our broad awareness and in-field expertise!
It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in certain good mount which also functions to be a warmth sink. More substantial crystals usually are utilized for side pumping e.g. with large-electricity diode bars.
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。
