The most typical laser-active uncommon earth ions and host media along with some normal emission wavelengths are demonstrated in the following desk:
These ions permit the crystal to amplify mild on the laser wavelength by way of stimulated emission, when Vitality is supplied to the crystal by using absorption of pump light-weight (�?optical pumping
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the upper-point out 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。
A superior floor good quality is naturally critical. Requirements of area flatness tend to be better than . This assists to stay away from both of those scattering losses and wavefront distortions which often can degrade the laser's beam high quality. On top of that, scratch and dig specs
The utmost doable doping concentration can count strongly on the host materials and its fabrication technique.
Laser modeling and simulation can be employed to reliably establish the the best possible crystal dimensions, doping density And maybe values of supplemental parameters.
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。

In 2017, we created the planet’s biggest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with extremely large more info emission spectra drives the event of laser diode pumped ultrafast strong-point out lasers. With the increase in pulse Power, peak ability, and repetition charge of strong-condition lasers, laser crystals will develop towards larger sized measurements, greater crystal quality, and controllable vital general performance.
There may be an array of crystalline media, which can be grouped according to big atomic constituents and crystalline structures. Some vital groups of crystals are:
