Obvious good-state lasers according to laser crystals are compact and light. Lasers from deep purple to blue are noted. Especially, there have been plenty of experiences on Pr3+ doped laser crystals, and steady wave lasers all-around 490 nm are already accomplished. Ti∶sapphire is the principle obtain crystal for ultrafast lasers. Superintense ultrafast lasers with peak energy starting from quite a few hundred terawatts to ten petawatts call for superior-top quality and huge-sized Ti∶sapphire crystal. The origin of defect similar optical absorption in Ti∶sapphire and The expansion of large-sized higher-good quality crystals are two essential troubles that urgently should be addressed. In recent years, we analyzed the mechanism of defect associated optical absorption in Ti∶sapphire theoretically, and grew huge-sized large-top quality crystals by way of heat exchange method. The main activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG could be the most generally utilised laser crystal. Recently, we explored a number of new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross section trouble of Nd∶Lu3Al5O12. SIOM described a whole new sort of laser crystal Yb∶GdScO3, of which the gain bandwidth is about eighty five nm. The typically used activation ions for 2 μm laser crystals are Tm3+ and Ho3+. Tm3+ can be specifically pumped by laser diode. Ho3+ has greater stimulated emission cross section, and its emission wavelength is longer than 2 μm. We analyzed the growth, spectroscopy, and laser effectiveness of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

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。
A significant floor quality is naturally vital. Specifications of area flatness are often better than . This aids to stop both equally scattering losses and wavefront distortions which can degrade the laser's beam quality. Additionally, scratch and dig specifications
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。
