The most common laser-active unusual earth ions and host media along with some regular emission wavelengths are revealed in the next table:
Right here you can submit queries and responses. So far as they get approved via the author, they are going to look earlier mentioned this paragraph together with the writer’s respond to. The writer will decide on acceptance determined by sure criteria. Primarily, The difficulty needs to be of adequately broad curiosity.
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。
Additionally, some flexibility is dropped in experiments if a person are unable to Check out absorbers with distinctive thickness or doping focus, as an example, without exchanging the laser crystal alone.
This is not hard to try and do: just find the lock icon before the URL within the address bar and drag that to your bookmark toolbar Together with the mouse. In case you discover the bookmark entry far too lengthy, you may ideal-click it to edit the text, e.g. making use of "RP Enc" in place of "RP Photonics Encyclopedia".
GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a wide number of specs. Apart from the effectively-established supplies, revolutionary crystals with exceptional Qualities like Yb:CALGO can open new horizons for demanding laser purposes. It doesn't matter whether or not individual parts for R & D needs are necessary or Price-efficient quantities in modest, medium or large batches with in-time supply to the output line are necessary: GWU’s focused services helps you to locate the very best Main factors for your Laser Crystal application.
A significant area excellent is of course crucial. Specifications of surface area flatness will often be better than . This aids to stop both of those scattering losses and wavefront distortions which may degrade the laser's beam top quality. Also, scratch and dig requirements
The maximum attainable doping concentration can rely strongly on the host substance and its fabrication technique.
Laser modeling and simulation may be used to reliably determine the optimum crystal Proportions, doping density And maybe values of added 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。

GWU-Lasertechnik has a lot more than thirty decades of encounter in distributing laser crystals. Pick GWU to get pleasure from our large knowledge and in-field working experience!
There exists an array of crystalline media, which may be grouped in accordance to important atomic constituents and crystalline constructions. 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。
