激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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 easy to do: just find the lock icon before the URL inside the address bar and drag that into the bookmark toolbar While using the mouse. In case you find the bookmark entry as well prolonged, you may ideal-simply click it to edit the text, e.g. making use of "RP Enc" as an alternative to "RP Photonics Encyclopedia".
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。
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 utmost possible doping concentration can count strongly around the host product and its fabrication technique.
Laser modeling and simulation can be employed to reliably establish the optimum crystal dimensions, doping density And perhaps values of supplemental parameters.
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。
It is obvious that distinctive applications lead to extremely distinct necessities on laser attain media. For this reason, a wide vary of various crystals are made use of, and creating the correct decision is essential for constructing lasers with the best possible effectiveness.
Different crystalline resources are incredibly distinctive regarding their hardness and various Homes, which identify with which strategies And just how easily they can be Lower and polished with top quality.
GWU-Lasertechnik has greater than 30 a long time of working experience in distributing laser crystals. Choose GWU to take advantage of our extensive know-how As well as in-subject practical experience!
It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It may be mounted in a few reliable mount which also functions to get more info be a warmth sink. Much larger crystals tend to be useful for aspect pumping e.g. with substantial-electricity diode bars.
