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。
On top of that, some flexibility is dropped in experiments if a person can't try out absorbers with distinct thickness or doping concentration, one example is, without the need of exchanging the laser crystal alone.
Which geometry, dopant and doping concentration from the obtain medium are most beneficial rely on numerous elements. The accessible pump source (kind of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the fabric itself also has some impact. By way of example, titanium–sapphire lasers must be pumped with high intensities, for which the form of the transversely cooled rod, operated with reasonably little pump and laser beam diameter, is much more acceptable than e.
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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
The host crystal is far more than simply a method to repair the laser-active ions at sure positions in space. Quite a more info few properties in the host substance are crucial:
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
All those surfaces that happen to be passed via the laser beam are Commonly both 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。
GWU-Lasertechnik has greater than 30 a long time of practical experience in distributing laser crystals. Pick out GWU to reap the benefits of our broad information and in-field encounter!
Applying our advertising package, you may Exhibit your logo, even further under your item description, and these will been observed by numerous photonics specialists.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
