Obvious good-condition lasers dependant on laser crystals are compact and lightweight. Lasers from deep red to blue are already noted. In particular, there were many stories on Pr3+ doped laser crystals, and constant wave lasers all over 490 nm are already achieved. Ti∶sapphire is the main obtain crystal for ultrafast lasers. Superintense ultrafast lasers with peak power ranging from various hundred terawatts to 10 petawatts need superior-good quality and large-sized Ti∶sapphire crystal. The origin of defect associated optical absorption in Ti∶sapphire and the growth of enormous-sized superior-quality crystals are two significant problems that urgently have to be tackled. Recently, we analyzed the mechanism of defect connected optical absorption in Ti∶sapphire theoretically, and grew substantial-sized higher-high-quality crystals as a result of warmth exchange method. The principle activating ions for 1 μm laser crystals are Nd3+ and Yb3+. Nd∶YAG could be the most generally used laser crystal. Lately, we explored numerous new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross portion challenge of Nd∶Lu3Al5O12. SIOM described a brand new sort of laser crystal Yb∶GdScO3, of which the gain bandwidth is about eighty five nm. The frequently utilized activation ions for two μm laser crystals are Tm3+ and Ho3+. Tm3+ could be right pumped by laser diode. Ho3+ has greater stimulated emission cross section, and its emission wavelength is for a longer period than 2 μm. We examined the growth, spectroscopy, and laser performance of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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。
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：
GWU presents all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) by using a broad range of specifications. Apart from the perfectly-set up products, progressive crystals with outstanding Houses like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of whether individual pieces for R & D reasons are expected or Price-economical quantities in little, medium or large batches with in-time supply to the manufacturing line are wanted: GWU’s devoted service helps you to locate the ideal core parts for your application.
A substantial area quality is needless to say critical. Technical specs of surface area flatness are sometimes much better than . This aids to click here prevent each scattering losses and wavefront distortions which may degrade the laser's beam high-quality. Also, scratch and dig specs
The maximum possible doping focus can depend strongly around the host material 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。

For quasi-a few-level laser gain media and even 3-level acquire media, a single usually ought to Restrict the length to a value that is also shorter for productive pump absorption, as reabsorption outcomes would or else spoil the efficiency. For side pumping, supplemental criteria occur into Participate in; Other than economical pump absorption, it can be crucial to get an acceptable spatial form from the gain profile.
