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。
The host crystal is a great deal more than just a method to fix the laser-active ions at specific positions in Area. Quite a few properties with the host content are essential:

People surfaces that are handed from the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.
Various crystalline products are quite various about their hardness and also other properties, which establish with which techniques And just how effortlessly they are often Reduce and polished with high quality.
In 2017, we created the planet’s biggest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with very wide emission spectra drives the event of laser diode website pumped ultrafast stable-condition lasers. With the increase in pulse Electrical power, peak ability, and repetition fee of sound-state lasers, laser crystals will establish towards more substantial sizes, higher crystal high-quality, and controllable critical functionality.
It could be oriented for close to perpendicular incidence with the laser beam, or at Brewster's angle. It can be fastened in certain sound mount which also functions as being a warmth sink. Larger crystals usually are used for side pumping e.g. with superior-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。
