Laser crystals are optical crystals �?typically one crystals (monocrystalline optical resources) �?which can be utilised as get media for strong-condition lasers. Generally, they are doped with possibly trivalent rare earth ions or changeover steel ions.
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the upper-point out lifetime.
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。
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
The utmost attainable doping concentration can count strongly about the host substance and its fabrication process.
Laser modeling and simulation can be utilized to reliably establish the ideal crystal Proportions, doping density And perhaps values of added parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is obvious that diverse apps bring about extremely different needs on laser obtain media. For this reason, a broad array of various crystals are utilised, and building the ideal click here selection is essential for constructing lasers with optimum performance.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
GWU-Lasertechnik has a lot more than 30 yrs of knowledge in distributing laser crystals. Select GWU to take pleasure in our vast knowledge and in-discipline experience!
It might be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It could be mounted in some strong mount which also acts for a heat sink. Bigger crystals are generally useful for aspect pumping e.g. with higher-power diode bars.
