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。
Moreover, some adaptability is shed in experiments if a single simply cannot Check out absorbers with different thickness or doping focus, as an example, without exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise the upper-condition life time.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
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。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Several laser crystal materials are actually demonstrated where some saturable absorber content is incorporated for passive Q switching of a laser.
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。
It is apparent that diverse purposes result in really unique prerequisites on laser gain media. Because of this, a wide variety of different crystals are utilised, and earning the right option is essential for developing lasers with the best possible efficiency.

The medium ought to have a high transparency (small absorption and scattering) inside the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this depends upon the quality of the fabric, determined by aspects of your fabrication process.
It might be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It could be mounted in some solid mount which also functions as being a heat sink. Greater crystals tend to be employed for facet pumping e.g. with high-ability diode bars.
