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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
A handful of laser crystal resources happen to be shown exactly where some saturable absorber substance is incorporated for passive Q switching of a laser.
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 purposes result in very distinctive prerequisites on laser get media. For that reason, a broad range of various crystals are utilized, and earning the ideal alternative is essential for constructing lasers with the best possible functionality.

In 2017, we developed the world’s most significant Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with exceptionally huge emission spectra drives the development of laser diode pumped ultrafast solid-condition lasers. With the increase in pulse Power, peak electrical power, and repetition charge of good-condition lasers, laser crystals will create in the direction of larger sized dimensions, greater crystal high-quality, and controllable crucial overall performance.
You can find an array of website crystalline media, that may be grouped in accordance to important atomic constituents and crystalline structures. Some essential groups of crystals are:
