Noticeable solid-condition lasers depending on laser crystals are compact and lightweight. Lasers from deep purple to blue happen to be reported. In particular, there were loads of studies on Pr3+ doped laser crystals, and continuous wave lasers all over 490 nm are already achieved. Ti∶sapphire is the leading gain crystal for ultrafast lasers. Superintense ultrafast lasers with peak electricity starting from a number of hundred terawatts to 10 petawatts involve large-high-quality and large-sized Ti∶sapphire crystal. The origin of defect connected optical absorption in Ti∶sapphire and The expansion of huge-sized superior-high quality crystals are two critical issues that urgently must be dealt with. In recent times, we analyzed the mechanism of defect connected optical absorption in Ti∶sapphire theoretically, and grew massive-sized substantial-excellent crystals by warmth exchange approach. The key activating ions for 1 μm laser crystals are Nd3+ and Yb3+. Nd∶YAG would be the most widely made use of laser crystal. Recently, we explored various new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross area difficulty of Nd∶Lu3Al5O12. SIOM reported a new style of laser crystal Yb∶GdScO3, of which the achieve bandwidth is about 85 nm. The normally utilised activation ions for two μm laser crystals are Tm3+ and Ho3+. Tm3+ could be directly pumped by laser diode. Ho3+ has greater stimulated emission cross section, and its emission wavelength is for a longer period than 2 μm. We analyzed The expansion, spectroscopy, and laser effectiveness of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。

Laser crystals are optical crystals �?typically single crystals (monocrystalline optical supplies) �?which might be applied as get media for stable-condition lasers. Normally, They can be doped with possibly trivalent rare earth ions or transition metal ions.

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the upper-condition life span.

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。

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 far more than just a method to repair the laser-Lively ions at selected positions in space. Several Attributes from the host content are very important:

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 applications result in really distinct demands on laser gain media. Because of this, a broad variety of different crystals are made use of, and making the right preference is important for setting up lasers with optimum performance.

Diverse crystalline supplies are very diverse concerning their hardness along with other Houses, which ascertain with which solutions And the way quickly they may be cut and polished with high quality.

The medium must have a high transparency (very low absorption and scattering) while in the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this relies on the caliber of the material, based on specifics from Laser Crystal the fabrication approach.

It could be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It could be fastened in a few reliable mount which also acts like a heat sink. Bigger crystals are generally utilized for side pumping e.g. with high-ability 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。
