These ions allow the crystal to amplify light-weight for the laser wavelength through stimulated emission, when Power is supplied into the crystal by means of absorption of pump light (�?optical pumping

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the higher-state life span.

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。

Laser modeling and simulation may be used to reliably ascertain the optimum crystal Proportions, doping density And maybe values of added parameters.

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-amount laser achieve media and even a few-amount attain media, 1 typically really should Restrict the duration to a price which happens to be much too shorter for economical pump absorption, as reabsorption outcomes would if not spoil the performance. For facet pumping, more considerations appear into Perform; Moreover productive pump absorption, it can be crucial to get an appropriate spatial form from the acquire profile.

Unique crystalline components are extremely unique concerning their hardness and various Qualities, which identify with which strategies And exactly how effortlessly they are often Slash and polished with good quality.

The medium ought to have a significant transparency (lower absorption and scattering) within the wavelength locations of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is dependent upon the quality of the material, based on aspects Laser Crystal on the fabrication procedure.

There may be a variety of crystalline media, which can be grouped according to important atomic constituents and crystalline structures. Some critical teams of crystals are:

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。
