Which geometry, dopant and doping focus on the attain medium are most beneficial count on quite a few components. The obtainable pump source (form of laser diode or lamp) along with the envisaged pumping arrangement are essential factors, but the fabric itself also has some affect. As an example, titanium–sapphire lasers have to be pumped with large intensities, for which the shape of a transversely cooled rod, operated with rather smaller pump and laser beam diameter, is more ideal than e.

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 couple of laser crystal resources are demonstrated exactly where some saturable absorber material is included 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。

Diverse crystalline components are very diverse concerning their hardness and also other properties, which decide with which solutions and how simply they may be cut and polished with good quality.

In 2017, we made the entire world’s major 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 extremely extensive emission spectra drives the event of laser diode pumped ultrafast solid-state lasers. With the increase in pulse Strength, peak ability, and repetition price of sound-condition lasers, laser crystals will acquire to larger sizes, greater crystal top quality, and controllable crucial functionality.

You can find a here wide range of crystalline media, which can be grouped in accordance to important atomic constituents and crystalline structures. Some critical teams of crystals are:

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。
