The most common laser-active unusual earth ions and host media together with some usual emission wavelengths are shown in the following table:

Here you could post issues and comments. In terms of they get accepted because of the creator, they'll show up previously mentioned this paragraph together with the writer’s remedy. The author will make a decision on acceptance dependant on certain criteria. Essentially, The difficulty have to be of adequately wide fascination.

Laser crystals are optical crystals �?normally single crystals (monocrystalline optical components) �?which might be employed as get media for reliable-state lasers. Most often, They are really doped with either trivalent scarce earth ions or transition metal ions.

This is simple to perform: just discover the lock icon before the URL within the handle bar and drag that to the bookmark toolbar While using the mouse. In the event you discover the bookmark entry far too extensive, you could appropriate-click it to edit the text, e.g. making use of "RP Enc" rather than "RP Photonics Encyclopedia".

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 A further illustration, Q-switched lasers access a greater population density during the upper laser amount and therefore are hence far more sensitive to quenching outcomes and energy transfer processes; for that reason, a lower doping density is usually suitable for these equipment. For high-electrical power lasers, reduced doping densities will often be used to limit the density of warmth technology, Even though skinny-disk lasers get the job done very best with hugely doped crystals. Quite a few laser products never reach the total effectiveness opportunity simply because this kind of details have not been thoroughly labored 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。

It is more info apparent that various purposes bring on very different requirements on laser obtain media. Due to this, a broad array of various crystals are applied, and making the proper decision is important for constructing lasers with ideal effectiveness.

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 greater than 30 yrs of working experience in distributing laser crystals. Choose GWU to benefit from our huge know-how As well as in-area working experience!

It may be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It may be mounted in a few solid mount which also acts like a heat sink. More substantial crystals usually are useful for aspect pumping e.g. with significant-ability 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。
