These tables contain only the most typical host crystals; lots of Other people exist, which happen to be significantly less commonly used.
These ions allow the crystal to amplify light-weight at the laser wavelength via stimulated emission, when Electricity is equipped towards the crystal by using absorption of pump gentle (�?optical pumping
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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 concentration of your acquire medium are most advantageous rely on numerous aspects. The readily available pump supply (style of laser diode or lamp) plus the envisaged pumping arrangement are crucial elements, but the material itself also has some affect. One example is, titanium–sapphire lasers need to be pumped with higher intensities, for which the shape of the transversely cooled rod, operated with somewhat compact pump and laser beam diameter, is much more suitable than e.

Naturally, it is rather appealing that a offered crystal high quality is produced continuously, Whilst diverse laser patterns can have another sensitivity to substance parameters.
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。
Laser modeling and simulation can be used to reliably ascertain the optimum crystal Proportions, doping density And maybe values of added parameters.
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-3-amount laser acquire media or even 3-level get media, a single often ought to limit the size to Laser Crystal a value which happens to be also shorter for productive pump absorption, as reabsorption consequences would in any other case spoil the performance. For side pumping, more concerns arrive into Enjoy; besides productive pump absorption, it is important to obtain an acceptable spatial condition of the gain profile.
Distinct crystalline materials are incredibly distinctive relating to their hardness together with other Homes, which decide with which solutions And the way simply they are often Slash and polished with good quality.
GWU-Lasertechnik has a lot more than thirty decades of encounter in distributing laser crystals. Opt for GWU to take pleasure in our wide knowledge As well as in-area practical experience!
Working with our marketing deal, you are able to Exhibit your logo, even more down below your merchandise description, and these will been seen by several photonics industry experts.
