So far as they get approved via the creator, they will seem over this paragraph together with the author’s solution. The writer will choose acceptance based upon selected conditions. Primarily, The problem need to be of adequately broad fascination.
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。
Furthermore, some overall flexibility is dropped in experiments if one can't try out absorbers with distinct thickness or doping concentration, one example is, with no exchanging the laser crystal alone.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

A high surface high quality is naturally critical. Technical specs of surface area flatness are often better than . This assists to prevent equally scattering losses and wavefront distortions that may degrade the laser's beam high quality. On top of that, scratch and dig technical specs
The maximum possible doping focus can rely strongly on the host substance and its fabrication approach.
The host crystal is far more than simply a means to repair the laser-active ions at sure positions in Room. Numerous Qualities of your host substance are essential:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
It is obvious that diverse programs result in extremely different prerequisites on laser attain media. This is why, a broad variety of various crystals are applied, and generating the correct selection is important for setting up lasers with optimum performance.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium should have a higher transparency (minimal absorption and scattering) from the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined Laser Crystal by the caliber of the material, determined by particulars from the fabrication procedure.
It might be oriented for in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It could be preset in some strong mount which also acts being a warmth sink. Much larger crystals are often utilized for side pumping e.g. with higher-electrical power diode bars.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
