Seen stable-state lasers according to laser crystals are compact and light-weight. Lasers from deep red to blue have been documented. Especially, there have been plenty of stories on Pr3+ doped laser crystals, and continual wave lasers about 490 nm are already accomplished. Ti∶sapphire is the leading get crystal for ultrafast lasers. Superintense ultrafast lasers with peak power ranging from a number of hundred terawatts to 10 petawatts need substantial-quality and large-sized Ti∶sapphire crystal. The origin of defect similar optical absorption in Ti∶sapphire and the growth of large-sized significant-top quality crystals are two vital troubles that urgently have to be resolved. Lately, we analyzed the mechanism of defect related optical absorption in Ti∶sapphire theoretically, and grew significant-sized significant-quality crystals via heat exchange method. The principle activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG is the most widely employed laser crystal. In recent times, we explored quite a few new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross section challenge of Nd∶Lu3Al5O12. SIOM described a new type of laser crystal Yb∶GdScO3, of which the get bandwidth is about 85 nm. The typically utilised activation ions for 2 μm laser crystals are Tm3+ and Ho3+. Tm3+ might be straight pumped by laser diode. Ho3+ has much larger stimulated emission cross portion, and its emission wavelength is longer than two μm. We analyzed the growth, spectroscopy, and laser overall performance of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

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 in addition the higher-state lifetime.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

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。

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。

For quasi-a few-degree laser achieve media or maybe three-amount acquire media, one often must limit the size to a price and that is too small for productive pump absorption, as reabsorption effects would otherwise spoil the performance. For facet pumping, extra issues come into Perform; In addition to successful pump absorption, it's important to obtain an acceptable spatial form of the website gain profile.

Distinct crystalline supplies are certainly distinctive regarding their hardness and also other properties, which establish with which techniques And exactly how very easily they are often Slice and polished with good quality.

GWU-Lasertechnik has much more than thirty a long time of expertise in distributing laser crystals. Select GWU to benefit from our wide knowledge and in-subject practical experience!

With that concept, a person doesn't want an extra saturable absorber crystal, making sure that one might make far more compact Q-switched laser setups with lessen interior parasitic losses. Nonetheless, undesired side effects could also happen, including getting unwelcome valence states of your associated ions or Electricity 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。
