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 thin disk. As One more case in point, Q-switched lasers achieve an increased populace density from the higher laser level and therefore are for that reason extra sensitive to quenching effects and Vitality transfer processes; thus, a lessen doping density is often suitable for these devices. For prime-electric power lasers, decreased doping densities are often utilized to limit the density of heat technology, Whilst slender-disk lasers do the job finest with remarkably doped crystals. A lot of laser merchandise usually do not reach the comprehensive general performance likely since these facts haven't been appropriately labored out.

Some laser crystal elements are shown in which some saturable absorber materials is integrated for passive Q switching of the laser.

For quasi-3-level laser attain media or maybe three-stage acquire media, a person typically must Restrict the duration to a price that is far too brief for economical pump absorption, as reabsorption effects would usually spoil the functionality. For facet pumping, extra issues occur into play; Aside from successful pump absorption, it's important to obtain a suitable spatial shape in the achieve profile.

For different factors, composite crystals are becoming well-known. These Have got a spatially different chemical composition and may be designed with Distinctive styles.

It may be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It can be fixed in some solid Laser Crystal mount which also functions as a warmth sink. Larger sized crystals tend to be employed for aspect pumping e.g. with higher-energy diode bars.

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。
