The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-state lifetime.
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 another instance, Q-switched lasers achieve an increased inhabitants density during the higher laser level and are consequently much more sensitive to quenching effects and Power transfer processes; consequently, a reduce doping density is often appropriate for these devices. For top-ability lasers, lessen doping densities will often be utilized to Restrict the density of heat generation, Even though thin-disk lasers work most effective with remarkably doped crystals. Quite a few laser merchandise usually do not get to the total efficiency possible because these types of facts have not been properly labored out.
A number of laser crystal components have been shown exactly where some saturable absorber product is integrated for passive Q switching of the laser.
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。
Individuals surfaces which might be handed by the laser beam are Ordinarily either oriented at Brewster's angle or have an anti-reflection coating.
