The most common laser-Lively unusual earth ions and host media along with some usual emission wavelengths are demonstrated in the following desk:
These ions permit the crystal to amplify light-weight on the laser wavelength through stimulated emission, when Power is provided to the crystal by means of absorption of pump mild (�?optical pumping
Laser crystals are optical crystals �?commonly single crystals (monocrystalline optical components) �?which might be employed as get media for stable-state lasers. In most cases, they are doped with both trivalent rare earth ions or changeover metallic ions.
On top of that, some flexibility is misplaced in experiments if just one simply cannot Check out absorbers with distinct thickness or doping concentration, one example is, with no exchanging the laser crystal by itself.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the higher-condition life time.
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。
The most doable doping focus can depend strongly around the host substance and its fabrication strategy.
A few laser crystal supplies here are already demonstrated where by some saturable absorber product is included 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。
Individuals surfaces which might be handed through the laser beam are Usually both oriented at Brewster's angle or have an anti-reflection coating.
Unique crystalline elements are quite distinct concerning their hardness and also other Homes, which decide with which techniques And exactly how quickly they can be cut and polished with good quality.
For various reasons, composite crystals are getting to be well-liked. These Possess a spatially varying chemical composition and might be created with Unique designs.
It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It might be set in some solid mount which also functions to be a warmth sink. More substantial crystals are generally useful for aspect pumping e.g. with substantial-power diode bars.
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。
