Obvious stable-state lasers dependant on laser crystals are compact and light-weight. Lasers from deep red to blue are reported. In particular, there have been a lot of experiences on Pr3+ doped laser crystals, and continuous wave lasers all around 490 nm have been reached. Ti∶sapphire is the key gain crystal for ultrafast lasers. Superintense ultrafast lasers with peak electricity starting from a number of hundred terawatts to 10 petawatts call for substantial-excellent and large-sized Ti∶sapphire crystal. The origin of defect relevant optical absorption in Ti∶sapphire and the growth of enormous-sized high-good quality crystals are two essential problems that urgently need to be resolved. Recently, we analyzed the mechanism of defect related optical absorption in Ti∶sapphire theoretically, and grew huge-sized high-excellent crystals by way of heat Trade approach. The primary activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG will be the most generally employed laser crystal. Lately, we explored many new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross area difficulty of Nd∶Lu3Al5O12. SIOM described a completely new style of laser crystal Yb∶GdScO3, of which the attain bandwidth is about 85 nm. The frequently used activation ions for two μm laser crystals are Tm3+ and Ho3+. Tm3+ might be straight pumped by laser diode. Ho3+ has larger sized stimulated emission cross part, and its emission wavelength is extended than 2 μm. We examined the growth, spectroscopy, and laser overall performance of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

A significant surface high quality is certainly essential. Specs of surface flatness are sometimes better than . This allows to avoid both of those scattering losses and wavefront distortions which often can degrade the laser's beam top quality. In addition, scratch and dig requirements
The utmost probable doping focus can rely strongly around the host product and its fabrication technique.
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。

In 2017, we developed the planet’s premier Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with very vast here emission spectra drives the development of laser diode pumped ultrafast solid-state lasers. With the rise in pulse Strength, peak electric power, and repetition fee of sound-state lasers, laser crystals will create to larger sized sizes, bigger crystal top quality, and controllable vital general performance.
Employing our promoting offer, you could Exhibit your emblem, additional below your product or service description, and these will been found by lots of photonics professionals.
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。
