The most typical laser-Energetic uncommon earth ions and host media along with some normal emission wavelengths are demonstrated in the subsequent desk:
These ions empower the crystal to amplify light-weight within the laser wavelength via stimulated emission, when energy is supplied to the crystal via 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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the upper-state life span.

Obviously, it is vitally appealing that a presented crystal quality is developed continuously, Though unique laser designs may have a unique sensitivity to material parameters.
g. a thin disk. As another example, Q-switched lasers reach the next inhabitants density from the higher laser level and are consequently much more delicate to quenching outcomes and Electrical power transfer procedures; as a result, a reduce doping density is commonly suitable for these products. For top-energy lasers, decreased doping densities tend to be utilized to Restrict the density of heat technology, Whilst slender-disk lasers operate greatest with really doped crystals. Several laser items never reach the total general performance probable because these kinds of aspects haven't been properly worked out.
The host crystal is a great deal more than simply a way to fix the laser-active ions at sure positions in House. Many Houses on the host materials are important:
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。
People surfaces that are handed with the laser beam are normally either oriented at Brewster's angle or have an anti-reflection coating.

For a variety of factors, composite crystals are getting to be well-known. These Use a spatially varying chemical composition and may be built with Unique designs.
It may be oriented for near perpendicular incidence of your laser beam, or at Brewster's angle. It might be fastened in a few sound mount which also functions for a heat sink. Larger crystals are usually employed for side pumping e.g. with high-electric power diode bars.
