The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the higher-condition 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。
The most probable doping concentration can count strongly over the host product and its fabrication method.
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。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
It is apparent that various programs bring on pretty distinctive requirements on laser gain media. here For this reason, a wide vary of various crystals are utilised, and generating the correct selection is essential for developing lasers with ideal efficiency.
