The most common laser-Lively unusual earth ions and host media together with some standard emission wavelengths are demonstrated in the subsequent desk:
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。
Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical elements) �?that happen to be employed as gain media for stable-state lasers. Typically, They may be doped with possibly trivalent rare earth ions or transition metal ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
This is not difficult to perform: just discover the lock icon in front of the URL during the address bar and drag that towards the bookmark toolbar Along with the mouse. In case you find the bookmark entry way too long, you'll be able to suitable-simply click it to edit the text, e.g. making use of "RP Enc" in place of "RP Photonics Encyclopedia".

A large area excellent is certainly vital. Requirements of area flatness tend to be much better than . This helps in order to avoid both equally scattering losses and wavefront distortions which might degrade the laser's beam high get more info quality. On top of that, scratch and dig requirements
The maximum possible doping focus can depend strongly over the host content and its fabrication technique.
The host crystal is a great deal more than simply a means to fix the laser-Energetic ions at selected positions in Area. Many Attributes in the host substance are crucial:
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 apps cause extremely diverse demands on laser attain media. Due to this, a wide range of various crystals are applied, and generating the appropriate selection is essential for setting up lasers with the best possible functionality.
