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 changeover cross-sections of pump and laser transitions and also the upper-condition life time.

A superior area quality is obviously essential. Specs of floor flatness in many cases are a lot better than . This assists in order to avoid the two scattering losses and wavefront distortions which might degrade the laser's beam top quality. Additionally, scratch and dig technical specs
g. a thin disk. As One more case in point, Q-switched lasers reach a greater populace density while in the higher laser stage and so are hence more sensitive to quenching results and Electricity transfer procedures; hence, a lessen doping density is commonly suitable for these products. For prime-electrical power lasers, reduced doping densities will often be accustomed to limit the density of warmth era, Despite the fact that skinny-disk lasers work most effective with highly doped crystals. Many laser products never reach the full general performance likely simply because these types of specifics haven't been correctly worked out.
The host crystal is much more than simply a method to repair the laser-Lively ions at sure positions in space. Numerous Qualities in the host content are very important:
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。
Those people surfaces that happen to be passed from the laser beam are Commonly more info either oriented at Brewster's angle or have an anti-reflection coating.

The medium must have a high transparency (very low absorption and scattering) within the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this will depend on the quality of the material, determined by aspects from the fabrication process.
With that concept, a person does not need to have an additional saturable absorber crystal, to ensure that just one might make additional compact Q-switched laser setups with lessen inner parasitic losses. Nonetheless, unwelcome side effects may come about, including getting unwanted valence states on the concerned ions or energy transfers.
