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。

Which geometry, dopant and doping focus of your acquire medium are most beneficial count on a number of aspects. The obtainable pump resource (type of laser diode or lamp) plus the envisaged pumping arrangement are crucial factors, but the fabric alone also has some influence. As an example, titanium–sapphire lasers need to be pumped with large intensities, for which the form of the transversely cooled rod, operated with relatively tiny pump and laser beam diameter, is much more ideal than e.

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 possible doping concentration can rely strongly around the host content and its fabrication technique.
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。
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
All those surfaces that happen to be passed via the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.
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。
The medium must have a substantial transparency (lower absorption and scattering) while in the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this depends on the quality of the material, determined by details from the fabrication method.
With That idea, one doesn't require an extra saturable absorber crystal, in order that 1 may make additional compact Q-switched laser setups with lessen inside parasitic losses. Nevertheless, unwelcome Unintended effects could also occur, including getting undesired valence states more info from the concerned ions or Electrical power transfers.
