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 focus of your get medium are most beneficial depend on a number of things. The obtainable pump supply (kind of laser diode or lamp) plus the envisaged pumping arrangement are very important variables, but the fabric itself also has some influence. By way of example, titanium–sapphire lasers need to be pumped with large intensities, for which the shape of a transversely cooled rod, operated with reasonably little pump and laser beam diameter, is a lot more appropriate than e.

GWU provides all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a wide range of requirements. Moreover the very well-recognized elements, impressive crystals with remarkable Homes like Yb:CALGO can open new horizons for demanding laser programs. Regardless of regardless of whether personal pieces for R & D applications are expected or Charge-productive numbers in modest, medium or significant batches with in-time shipping and delivery with the generation line are essential: GWU’s dedicated company helps you to discover the most effective core components in your application.

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

The most feasible doping concentration can rely strongly on the host material 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-3-amount laser gain media or perhaps 3-stage gain media, 1 frequently ought to limit the duration to a worth that is way too limited for efficient pump absorption, as reabsorption consequences would if not spoil the overall performance. For side pumping, supplemental things to consider occur into Enjoy; Aside from efficient pump absorption, it is important to obtain a suitable spatial form on the achieve profile.
