Seen good-point out lasers based on laser crystals are compact and light-weight. Lasers from deep pink to blue are already described. In particular, there were a great deal of studies on Pr3+ doped laser crystals, and steady wave lasers all around 490 nm have already been achieved. Ti∶sapphire is the primary achieve crystal for ultrafast lasers. Superintense ultrafast lasers with peak electricity ranging from various hundred terawatts to ten petawatts call for higher-high-quality and large-sized Ti∶sapphire crystal. The origin of defect related optical absorption in Ti∶sapphire and the growth of enormous-sized large-excellent crystals are two important problems that urgently have to be addressed. In recent years, we analyzed the mechanism of defect related optical absorption in Ti∶sapphire theoretically, and grew big-sized substantial-good quality crystals via warmth exchange system. The most crucial activating ions for 1 μm laser crystals are Nd3+ and Yb3+. Nd∶YAG may be the most generally applied laser crystal. In recent years, we explored various new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross area trouble of Nd∶Lu3Al5O12. SIOM described a fresh kind of laser crystal Yb∶GdScO3, of which the obtain bandwidth is about eighty five nm. The usually made use of activation ions for 2 μm laser crystals are Tm3+ and Ho3+. Tm3+ is often instantly pumped by laser diode. Ho3+ has bigger stimulated emission cross part, and its emission wavelength is for a longer period than two μm. We researched the growth, spectroscopy, and laser effectiveness of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

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（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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
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。
g. a thin disk. As another example, Q-switched lasers arrive at an increased populace density within the higher laser level and therefore are consequently a lot more sensitive to quenching consequences and Strength transfer procedures; as a result, a lessen doping density is frequently suitable for these units. For top-electric power lasers, decreased doping densities will often be used to limit the density of warmth technology, Though skinny-disk lasers get the job done very best with hugely doped crystals. Lots of laser solutions will not reach the whole overall performance potential for the reason that these types of particulars haven't been thoroughly worked out.
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。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
