These tables consist of only the most common host crystals; quite a few Other individuals exist, which might be a lot less frequently utilised.

These ions help the crystal to amplify light at the laser wavelength by way of stimulated emission, when Electrical power is equipped to the crystal by means of absorption of pump light (�?optical pumping

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。

This is a snap to carry out: just find the lock icon in front of the URL inside the tackle bar and drag that for the bookmark toolbar with the mouse. In the event you locate the bookmark entry as well very long, you'll be able to suitable-click it to edit the text, e.g. making use of "RP Enc" in lieu of "RP Photonics Encyclopedia".

GWU presents all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) having a broad assortment of requirements. Aside from the properly-set up supplies, innovative crystals with excellent properties like Yb:CALGO can open up new horizons for demanding laser programs. Regardless of regardless of whether individual pieces for R & D purposes are demanded or Value-effective numbers in smaller, medium or huge batches with in-time delivery for that manufacturing line are desired: GWU’s committed services helps you to find the ideal Main components in your software.

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。

Some laser crystal components are actually 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。

For quasi-three-level laser attain media or maybe three-amount get media, one particular frequently really should limit the length to a worth that's as well shorter for productive pump absorption, as reabsorption effects would otherwise spoil the functionality. For side pumping, more factors arrive into Participate in; Other than effective pump absorption, it's important to acquire an acceptable spatial condition from the get profile.

The medium should have a high transparency (reduced absorption and scattering) inside the wavelength locations of pump website and laser radiation, and superior optical homogeneity. To some extent, this relies on the standard of the fabric, determined by aspects on the fabrication procedure.

With that concept, just one isn't going to have to have a further saturable absorber crystal, so that one could make more compact Q-switched laser setups with lessen inside parasitic losses. Even so, unwanted Unwanted effects can also occur, for instance obtaining unwelcome valence states in the associated 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。
