These ions enable the crystal to amplify light for the laser wavelength via stimulated emission, when Vitality is supplied to your crystal through absorption of pump light (�?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 on the attain medium are most beneficial rely on quite a few variables. The accessible pump resource (sort of laser diode or lamp) and the envisaged pumping arrangement are very important factors, but the material alone also has some influence. Such as, titanium–sapphire lasers must be pumped with superior intensities, for which the form of the transversely cooled rod, operated with relatively modest pump and laser beam diameter, is a lot more proper than e.

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。
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。
The host crystal is a great deal more than just a method to fix the laser-Lively ions at specific positions in House. Quite a few properties on the host material are essential:

All those surfaces which can be passed via the laser beam are Generally either oriented at Brewster's angle or have an anti-reflection coating.
Diverse crystalline components are very unique regarding their hardness and various Homes, which determine with which procedures and how quickly they can be Slice and polished with good quality.
GWU-Lasertechnik has much more than 30 yrs of knowledge in distributing laser crystals. Select GWU to take advantage of our vast expertise As well as in-subject practical experience!
With that concept, a person won't will Laser Crystal need an extra saturable absorber crystal, to ensure a single might make extra compact Q-switched laser setups with decrease internal parasitic losses. Nevertheless, unwelcome Unintended effects could also manifest, like getting unwelcome valence states in the associated ions or Power transfers.
