The most common laser-Energetic scarce earth ions and host media along with some standard emission wavelengths are revealed in the following 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。

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

Also, some flexibility is shed in experiments if a person simply cannot Check out absorbers with various thickness or doping focus, by way of example, with out exchanging the laser crystal alone.

Which geometry, dopant and doping focus in the get medium are most beneficial depend on quite a few things. The offered pump supply (style of laser diode or lamp) along with the envisaged pumping arrangement are very important things, but the material alone also has some influence. Such as, titanium–sapphire lasers should be pumped with large intensities, for which the form of a transversely cooled rod, operated with rather modest pump and laser beam diameter, is a lot more appropriate than e.

Of course, it is very desirable that a supplied crystal quality is developed continuously, Despite the fact that various laser layouts can have a unique sensitivity to materials parameters.

The most attainable doping focus can depend strongly over the host material and its fabrication technique.

A handful click here of laser crystal components are demonstrated in which some saturable absorber materials is included for passive Q switching of a laser.

激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

All those surfaces that happen to be handed with the laser beam are normally either oriented at Brewster's angle or have an anti-reflection coating.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

For different factors, composite crystals are becoming preferred. These have a spatially various chemical composition and might be designed with Distinctive styles.

Using our advertising package, it is possible to Display screen your logo, more underneath your solution description, and these will been seen by several photonics pros.

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。
