Obvious stable-condition lasers based upon laser crystals are compact and light-weight. Lasers from deep red to blue happen to be noted. Specially, there have been a great deal of reviews on Pr3+ doped laser crystals, and continuous wave lasers all over 490 nm have already been obtained. Ti∶sapphire is the principle gain crystal for ultrafast lasers. Superintense ultrafast lasers with peak ability ranging from many hundred terawatts to 10 petawatts need substantial-top quality and huge-sized Ti∶sapphire crystal. The origin of defect linked optical absorption in Ti∶sapphire and The expansion of huge-sized superior-high quality crystals are two crucial difficulties that urgently should be dealt with. Recently, we analyzed the system of defect similar optical absorption in Ti∶sapphire theoretically, and grew substantial-sized superior-top quality crystals by means of heat exchange method. The primary activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG is definitely the most generally utilised laser crystal. In recent times, we explored a number of new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross section trouble of Nd∶Lu3Al5O12. SIOM documented a fresh kind of laser crystal Yb∶GdScO3, of which the gain bandwidth is about eighty five nm. The frequently utilized activation ions for two μm laser crystals are Tm3+ and Ho3+. Tm3+ could be directly pumped by laser diode. Ho3+ has much larger stimulated emission cross segment, and its emission wavelength is more time than two μm. We researched The expansion, spectroscopy, and laser functionality of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the upper-point out lifetime.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
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。
It is clear that distinctive purposes produce pretty unique prerequisites on laser get media. This is why, a broad assortment of different crystals are made use of, and building the best selection is essential for constructing lasers with the best possible efficiency.
Diverse crystalline products are extremely distinctive regarding their hardness and other Homes, which determine with which approaches and how very easily they may be cut and polished click here with high quality.
The medium ought to have a substantial transparency (reduced absorption and scattering) in the wavelength locations of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the quality of the material, based on information of the fabrication approach.
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It may be set in a few sound mount which also acts like a heat sink. Greater crystals are generally utilized for side pumping e.g. with high-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。
