Fascination About Laser Crystal
The most common laser-active exceptional earth ions and host media along with some common emission wavelengths are demonstrated in the next table: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。

Which geometry, dopant and doping concentration of your get medium are most useful rely on many aspects. The obtainable pump resource (sort of laser diode or lamp) as well as envisaged pumping arrangement are essential variables, but the fabric alone also has some influence. One example is, titanium–sapphire lasers need to be pumped with high intensities, for which the shape of a transversely cooled rod, operated with rather small pump and laser beam diameter, is much more suitable than e.
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 attainable doping focus can rely strongly on the host materials and its fabrication approach.
A handful click here of laser crystal components happen to be shown where some saturable absorber content is integrated for passive Q switching of the laser.
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 clear that various apps bring about extremely different requirements on laser achieve media. Due to this, a wide vary of various crystals are used, and creating the correct alternative is important for setting up lasers with the best possible performance.
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。
