Noticeable strong-point out lasers according to laser crystals are compact and lightweight. Lasers from deep purple to blue happen to be reported. Primarily, there were a lot of studies on Pr3+ doped laser crystals, and constant wave lasers about 490 nm have been reached. Ti∶sapphire is the primary attain crystal for ultrafast lasers. Superintense ultrafast lasers with peak electricity starting from numerous hundred terawatts to 10 petawatts require large-high-quality and large-sized Ti∶sapphire crystal. The origin of defect connected optical absorption in Ti∶sapphire and The expansion of large-sized substantial-high-quality crystals are two essential troubles that urgently must be resolved. Recently, we analyzed the system of defect linked optical absorption in Ti∶sapphire theoretically, and grew substantial-sized superior-quality crystals through warmth Trade system. The leading activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG would be the most widely utilized laser crystal. In recent years, we explored quite a few new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross part dilemma of Nd∶Lu3Al5O12. SIOM described a whole new kind of laser crystal Yb∶GdScO3, of which the gain bandwidth is about 85 nm. The commonly Laser Crystal applied activation ions for 2 μm laser crystals are Tm3+ and Ho3+. Tm3+ is usually right pumped by laser diode. Ho3+ has bigger stimulated emission cross part, and its emission wavelength is for a longer time than two μm. We studied the growth, spectroscopy, and laser efficiency of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise the upper-state 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。
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。
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。
A handful of laser crystal supplies are actually demonstrated the place some saturable absorber material is integrated for passive Q switching of the laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
Individuals surfaces which happen to be passed from the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.
