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。

Which geometry, dopant and doping focus of the achieve medium are most beneficial count on several variables. The available pump source (variety of laser diode or lamp) and also the envisaged pumping arrangement are very important variables, but the material itself also has some affect. For instance, titanium–sapphire lasers must be pumped with higher intensities, for which the form of a transversely cooled rod, operated with rather smaller pump and laser beam diameter, is a lot more acceptable than e.

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。

Of course, it is extremely fascinating that a given crystal top quality is produced consistently, although distinctive laser models may have a special sensitivity to substance parameters.

The utmost doable doping focus can rely strongly over the host content and its fabrication strategy.

Laser modeling and simulation can be utilized to reliably determine the ideal crystal Proportions, doping density and possibly values of additional 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。

It is apparent that unique programs bring about extremely distinct requirements on laser achieve media. This is why, a broad variety of different crystals are made use of, and generating the ideal decision is essential for setting up lasers with optimum effectiveness.

In 2017, we developed the globe’s most significant Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with exceptionally wide emission spectra drives the development of laser diode pumped ultrafast stable-state lasers. With the rise in pulse Electrical power, peak energy, and repetition price of good-condition lasers, laser crystals will establish towards much larger dimensions, bigger crystal excellent, and controllable vital general performance.

You can find a variety of crystalline media, which can be grouped according to important atomic constituents and crystalline constructions. Some crucial groups of get more info 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。
