Seen sound-state lasers depending on laser crystals are compact and light. Lasers from deep purple to blue are documented. Specifically, there have been many reviews on Pr3+ doped laser crystals, and continuous wave lasers all over 490 nm have been realized. Ti∶sapphire is the key attain crystal for ultrafast lasers. Superintense ultrafast lasers with peak electric power starting from numerous hundred terawatts to 10 petawatts require substantial-high quality and huge-sized Ti∶sapphire crystal. The origin of defect similar optical absorption in Ti∶sapphire and The expansion of large-sized high-good quality crystals are two significant issues that urgently need to be addressed. In recent times, we analyzed the mechanism of defect associated optical absorption in Ti∶sapphire theoretically, and grew huge-sized high-top quality crystals by way of heat exchange technique. The main activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG would be the most widely made use of laser crystal. Recently, we explored quite a few new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross part dilemma of Nd∶Lu3Al5O12. SIOM noted a new variety of laser crystal Yb∶GdScO3, of which the gain bandwidth is about eighty five nm. The typically used activation ions for two μm laser crystals are Tm3+ and Ho3+. Tm3+ might be straight pumped by laser diode. Ho3+ has larger stimulated emission cross area, and its emission wavelength is lengthier than two μm. We examined the growth, spectroscopy, and laser general performance of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.
These ions allow the crystal to amplify light-weight within the laser wavelength by means of stimulated emission, when Electricity is provided towards the crystal by using absorption of pump mild (�?optical pumping
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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and also 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。
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。
The most achievable doping focus can depend strongly over the host content and its fabrication method.
A couple of laser crystal components have already been demonstrated where by some saturable absorber substance 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。

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium must have a high transparency (very low absorption and scattering) inside the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is dependent upon the quality of the check here material, based on specifics of the fabrication approach.
With That idea, one does not need an additional saturable absorber crystal, so that a person may perhaps make additional compact Q-switched laser setups with decrease inner parasitic losses. Even so, undesirable Unwanted effects might also occur, for instance obtaining unwelcome valence states in the associated ions or Strength transfers.
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。
