芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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。
Which geometry, dopant and doping focus in the gain medium are most advantageous rely on various variables. The offered pump resource (sort of laser diode or lamp) as well as the envisaged pumping arrangement are very important variables, but the material itself also has some impact. For instance, titanium–sapphire lasers ought to be pumped with large intensities, for which the form of the transversely cooled rod, operated with comparatively smaller pump and laser beam diameter, is a lot more suitable than e.
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。
A substantial area quality is not surprisingly important. Specifications of surface flatness are frequently a lot better than . This will help to stay check here away from both of those scattering losses and wavefront distortions which can degrade the laser's beam quality. In addition, scratch and dig specifications
The most attainable doping concentration 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。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
It is obvious that diverse apps bring on pretty distinctive requirements on laser acquire media. Because of this, a broad variety of different crystals are used, and making the right choice is important for setting up lasers with ideal efficiency.

In 2017, we created the whole world’s greatest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with very huge emission spectra drives the event of laser diode pumped ultrafast solid-state lasers. With the increase in pulse Strength, peak ability, and repetition price of sound-condition lasers, laser crystals will create in direction of bigger dimensions, larger crystal quality, and controllable critical functionality.
Using our promoting package, you'll be able to Exhibit your symbol, further down below your product description, and these will been seen by many photonics gurus.
