The commonest laser-active rare earth ions and host media together with some common emission wavelengths are demonstrated in the subsequent desk:
Listed here you can post inquiries and comments. So far as they get approved by the creator, they will look above this paragraph together with the creator’s solution. The writer will settle on acceptance dependant on selected criteria. Effectively, the issue must be of sufficiently broad desire.
Laser crystals are optical crystals �?usually single crystals (monocrystalline optical elements) �?which might be applied as gain media for strong-condition lasers. Most often, they are doped with either trivalent unusual earth ions or changeover metal ions.
Furthermore, some overall flexibility is misplaced in experiments if a single are unable to try out absorbers with distinctive thickness or doping concentration, for example, devoid of exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and also the higher-point out life span.
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。
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 happen to be shown the place some saturable absorber substance is integrated for passive Q switching of a laser.
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。

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 a lot more than thirty many years of practical experience in distributing laser crystals. Opt for GWU to take pleasure in our broad know-how As well as in-discipline encounter!
With That idea, one particular would not will need yet another saturable absorber crystal, so that a single could make a lot more compact Q-switched laser setups with lower inner parasitic losses. Nonetheless, undesired Unintended effects might also arise, more info such as acquiring unwelcome valence states of the concerned ions or Power transfers.
