The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-state life time.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
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。
g. a skinny disk. As An additional illustration, Q-switched lasers reach a better inhabitants density within the upper laser stage and they are therefore additional delicate to quenching effects and Power transfer processes; thus, a decreased doping density is frequently appropriate for these devices. For prime-electric power lasers, lessen doping densities are sometimes utilized to Restrict the density of heat generation, Even though slender-disk lasers function greatest with highly doped crystals. A lot of laser items usually do not reach the complete performance opportunity for the reason that these information have not been properly worked out.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。

GWU-Lasertechnik has in excess of thirty yrs of working experience in distributing laser crystals. Pick out GWU to benefit from our large knowledge As well as in-subject knowledge!
It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It might be preset in certain stable mount which also functions being a heat sink. Bigger crystals are generally used for here facet pumping e.g. with superior-ability diode bars.
