Which geometry, dopant and doping focus with the gain medium are most beneficial rely on various variables. The available pump source (style of laser diode or lamp) as well as envisaged pumping arrangement are essential variables, but the fabric alone also has some affect. For example, titanium–sapphire lasers should be pumped with higher intensities, for which the form of the transversely cooled rod, operated with fairly smaller pump and laser beam diameter, is more suitable 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 skinny disk. As An additional illustration, Q-switched lasers reach a better inhabitants density within the upper laser stage and therefore are hence much more sensitive to quenching results and Electricity transfer procedures; therefore, a decreased doping density is commonly suitable for these equipment. For high-energy lasers, reduce doping densities are sometimes accustomed to limit the density of heat generation, Even though thin-disk lasers function very best with very doped crystals. Numerous laser goods don't get to the full performance opportunity mainly because these kinds of specifics haven't been appropriately 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。

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。

For quasi-3-degree laser gain media or maybe 3-amount achieve media, a single often ought to limit the size to a worth that's as well small for effective pump absorption, as reabsorption outcomes would otherwise spoil the performance. For side pumping, additional issues come into Enjoy; In addition to successful pump absorption, it is vital to obtain a suitable spatial form of the get profile.

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。

GWU-Lasertechnik has over 30 several years of knowledge in read more distributing laser crystals. Select GWU to reap the benefits of our large information and in-industry encounter!

It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It may be mounted in a few sound mount which also functions for a warmth sink. More substantial crystals usually are employed for aspect pumping e.g. with higher-energy 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。
