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。
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。
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-level laser attain media as well as three-stage obtain media, one generally has to Restrict the duration to a worth that's as well small for effective pump absorption, as reabsorption outcomes would or else spoil the general performance. For side pumping, added considerations arrive into Enjoy; besides productive pump absorption, it can be crucial to obtain a suitable spatial shape in the get profile.

The medium must have a higher transparency (low absorption and scattering) from the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this relies on the caliber of the fabric, determined by facts from the fabrication system.
It could be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It can be mounted in a few good mount which also functions check here being a warmth sink. Bigger crystals tend to be used for side pumping e.g. with significant-electrical power 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。
