Which geometry, dopant and doping concentration of the gain medium are most advantageous depend on several factors. The offered pump resource (style of laser diode or lamp) plus the envisaged pumping arrangement are crucial variables, but the material alone also has some affect. As an example, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with reasonably tiny pump and laser beam diameter, is a lot more acceptable 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。

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。

g. a thin disk. As A different example, Q-switched lasers access a greater populace density in the upper laser stage and they are consequently far more delicate to quenching consequences and Power transfer processes; thus, a lower doping density is usually appropriate for these units. For prime-electricity lasers, decreased doping densities are often used to limit the density of warmth era, Despite the fact that slim-disk lasers operate ideal with hugely doped crystals. A lot of laser merchandise usually do not reach the comprehensive effectiveness possible get more info for the reason that these kinds of details have not been thoroughly worked out.

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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。

People surfaces that happen to be handed with the laser beam are Generally both oriented at Brewster's angle or have an anti-reflection coating.

GWU-Lasertechnik has in excess of thirty years of expertise in distributing laser crystals. Decide on GWU to take pleasure in our wide understanding and in-field encounter!

It might be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It can be set in some sound mount which also acts like a heat sink. Greater crystals are generally utilized for side pumping e.g. with high-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。
