Laser crystals are optical crystals �?normally one crystals (monocrystalline optical resources) �?which are applied as attain media for solid-point out lasers. In most cases, These are doped with both trivalent unusual earth ions or changeover metal 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。
This is a snap to complete: just discover the lock icon in front of the URL inside the handle bar and drag that to your bookmark toolbar While using the mouse. Just in case you locate the bookmark entry as well long, you are able to suitable-click it to edit the textual content, e.g. making use of "RP Enc" instead of "RP Photonics Encyclopedia".

A large surface quality is not surprisingly significant. Specifications of area flatness will often be a lot better than . This allows to stop each scattering losses and wavefront distortions that may degrade the laser's beam top quality. Furthermore, scratch and dig specs
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
A few laser crystal products are already demonstrated where by some saturable absorber material is integrated 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。
For quasi-3-degree laser obtain media or maybe 3-degree acquire media, 1 usually needs to Restrict the length to a price which is way too limited for productive pump absorption, as reabsorption consequences would or else spoil the functionality. For aspect pumping, additional criteria appear into Engage in; Apart from successful pump absorption, it is crucial to acquire a suitable spatial shape from the gain profile.

GWU-Lasertechnik has in excess of thirty decades of working experience in distributing laser crystals. Select GWU to take advantage of our broad awareness and in-field knowledge!
With That idea, a person isn't going to require a further saturable absorber crystal, so that a person could make more compact Q-switched click here laser setups with lower inner parasitic losses. Nonetheless, undesirable side effects might also arise, including obtaining unwanted valence states of the concerned ions or Strength transfers.
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。
