Laser Crystal - An Overview
Laser Crystal - An Overview
Blog Article
These tables have only the commonest host crystals; many Other folks exist, that are considerably less routinely utilized.
Listed here you could post thoughts and comments. As far as they get accepted from the author, they are going to show up above this paragraph along with the writer’s response. The writer will make a decision on acceptance dependant on sure conditions. Effectively, The difficulty have to be of sufficiently wide curiosity.
Laser crystals are optical crystals �?commonly one crystals (monocrystalline optical components) �?that are applied as obtain media for good-condition lasers. Most often, They may be doped with either 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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the upper-condition life span.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
A substantial floor excellent is certainly important. Specifications of area flatness will often be much better than . This allows to stay away from both of those scattering losses and wavefront distortions which may degrade the laser's beam good quality. Furthermore, scratch and click here dig requirements
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 the place some saturable absorber material is integrated for passive Q switching of the 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。
