Visible good-point out lasers dependant on laser crystals are compact and light-weight. Lasers from deep red to blue have already been reported. Especially, there have been lots of reviews on Pr3+ doped laser crystals, and continuous wave lasers all over 490 nm have already been accomplished. Ti∶sapphire is the main achieve crystal for ultrafast lasers. Superintense ultrafast lasers with peak energy starting from several hundred terawatts to ten petawatts have to have higher-good quality and enormous-sized Ti∶sapphire crystal. The origin of defect relevant optical absorption in Ti∶sapphire and The expansion of large-sized large-excellent crystals are two important concerns that urgently must be resolved. Recently, we analyzed the system of defect similar optical absorption in Ti∶sapphire theoretically, and grew large-sized higher-high quality crystals via heat exchange method. The primary activating ions for 1 μm laser crystals are Nd3+ and Yb3+. Nd∶YAG may be the most widely used laser crystal. Recently, we explored various new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross part difficulty of Nd∶Lu3Al5O12. SIOM noted a brand new variety of laser crystal Yb∶GdScO3, of which the obtain bandwidth is about 85 nm. The normally employed activation ions for two μm laser crystals are Tm3+ and Ho3+. Tm3+ might be right pumped by laser diode. Ho3+ has bigger stimulated emission cross portion, and its emission wavelength is more time than two μm. We researched The expansion, spectroscopy, and laser efficiency of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.
These ions empower the crystal to amplify light at the laser wavelength by using stimulated emission, when Electricity is supplied into the crystal through absorption of pump light (�?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。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the upper-condition 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。
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。

GWU-Lasertechnik has a lot more than thirty yrs of working experience in distributing laser crystals. Choose GWU to take advantage of our wide information and in-discipline expertise!
With that concept, 1 doesn't require a further saturable absorber crystal, to website make sure that just one may well make extra compact Q-switched laser setups with lessen inside parasitic losses. Even so, undesirable Unwanted side effects could also arise, like acquiring unwelcome valence states in the associated ions or Vitality 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。
