New Step by Step Map For Laser Crystal
These tables consist of only the most common host crystals; several Other folks exist, which might be considerably less often applied.Listed here you may post inquiries and opinions. So far as they get accepted through the author, they're going to seem higher than this paragraph together with the creator’s respond to. The writer will settle on acceptance based on particular conditions. Essentially, the issue should be of sufficiently wide 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。

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：
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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The most doable doping focus can rely strongly to the host material and its fabrication system.
A handful of laser crystal products have been shown the place some saturable absorber content is included for passive Q switching of a laser.
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 distinctive purposes produce quite diverse specifications on laser achieve media. For this reason, a wide vary of various crystals are used, and earning the correct selection is important for constructing lasers with ideal overall performance.

The medium ought to have a higher transparency (reduced absorption and scattering) during the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this relies on the quality of the material, determined by information of the fabrication procedure.
It may be oriented for in the vicinity of perpendicular incidence on the laser beam, or at Brewster's angle. It may be preset in some stable mount which also acts being a warmth sink. Larger crystals are frequently utilized for side more info 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。
