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。
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical products) �?that happen to be used as achieve media for good-condition lasers. Generally, These are doped with either trivalent uncommon earth ions or changeover metallic ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping concentration on the achieve medium are most beneficial depend upon various components. The readily available pump supply (sort of laser diode or lamp) as well as the envisaged pumping arrangement are important factors, but the fabric itself also has some impact. By way of example, titanium–sapphire lasers should be pumped with large intensities, for which the shape of the transversely cooled rod, operated with comparatively small pump and laser beam diameter, is more ideal 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。
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。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation can be used to reliably ascertain the optimum crystal Proportions, doping density and possibly values of extra 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-three-stage laser obtain media or even a few-level get media, one particular frequently really should limit the size to a value and that is as well small for effective pump absorption, as reabsorption consequences would in any other case spoil the performance. For side pumping, more considerations occur into play; In addition to economical pump absorption, it is crucial to acquire a suitable spatial shape from the achieve profile.

In 2017, we developed the earth’s largest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with extremely vast emission spectra drives the event of laser diode pumped ultrafast good-state lasers. With the increase in pulse Strength, peak energy, and repetition fee of strong-state lasers, laser crystals will produce to larger sizes, higher crystal top quality, and controllable crucial functionality.
It might be oriented for in close proximity to perpendicular incidence of your Laser Crystal laser beam, or at Brewster's angle. It might be fixed in certain good mount which also functions for a warmth sink. More substantial crystals are often utilized for side pumping e.g. with higher-power diode bars.
