These tables incorporate only the commonest host crystals; numerous Many others exist, that happen to be less regularly utilised.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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。
Additionally, some overall flexibility is lost in experiments if just one can not try out absorbers with various thickness or doping focus, for instance, with out exchanging the laser crystal alone.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the upper-condition life time.

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 utmost doable doping focus can rely strongly over the host material and its fabrication technique.
Laser modeling and simulation can be employed to reliably identify the ideal crystal Proportions, doping density And perhaps values of further 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。
For quasi-a few-stage laser achieve media or maybe 3-stage gain media, one frequently must Restrict the size to a worth and that is also quick for productive pump absorption, as reabsorption results would in any other case spoil the general performance. For side pumping, added factors come into Participate in; Other than economical pump absorption, it can be crucial to acquire an appropriate spatial condition in the get profile.

GWU-Lasertechnik has more than 30 a long time of knowledge in more info distributing laser crystals. Choose GWU to get pleasure from our extensive awareness As well as in-area knowledge!
It may be oriented for in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It can be fixed in some reliable mount which also functions like a heat sink. Greater crystals are usually used for aspect pumping e.g. with substantial-power diode bars.
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。
