These tables incorporate only the most common host crystals; a lot of Other folks exist, which can be a lot less commonly made use of.
These ions enable the crystal to amplify gentle with the laser wavelength by using stimulated emission, when Strength is provided to your crystal by means of absorption of pump light-weight (�?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 focus of the obtain medium are most useful depend on quite a few components. The obtainable pump source (variety of laser diode or lamp) plus the envisaged pumping arrangement are crucial variables, but the fabric by itself also has some influence. For instance, titanium–sapphire lasers must be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with rather little pump and laser beam diameter, is much more proper than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
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。
g. a skinny disk. As another case in point, Q-switched lasers achieve an increased population density while in the higher laser amount and therefore are thus much more sensitive to read more quenching outcomes and Electricity transfer processes; as a result, a decreased doping density is frequently appropriate for these devices. For top-electric power lasers, decreased doping densities are sometimes used to Restrict the density of warmth generation, although thin-disk lasers do the job ideal with hugely doped crystals. A lot of laser items tend not to get to the entire functionality probable mainly because these information have not been properly worked out.
A few laser crystal materials have been shown in which some saturable absorber content is integrated for passive Q switching of the laser.
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。
People surfaces that happen to be handed by the laser beam are normally possibly oriented at Brewster's angle or have an anti-reflection coating.

GWU-Lasertechnik has in excess of thirty decades of experience in distributing laser crystals. Select GWU to take pleasure in our extensive expertise and in-subject knowledge!
It might be oriented for in the vicinity of perpendicular incidence with the laser beam, or at Brewster's angle. It could be fastened in certain strong mount which also functions being a warmth sink. Greater crystals are generally useful for side pumping e.g. with high-electrical power diode bars.
