Furthermore, some overall flexibility is lost in experiments if just one can't Check out absorbers with various thickness or doping focus, by way of example, without having exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and also the upper-point out lifetime.
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。
Obviously, it is very appealing that a specified crystal high quality is generated persistently, Whilst various laser types might have a different sensitivity to content parameters.
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
A number of laser crystal materials have already been demonstrated exactly where some saturable absorber material is incorporated 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 click here various applications lead to pretty unique prerequisites on laser gain media. For that reason, a wide array of various crystals are utilised, and earning the right alternative is important for developing lasers with ideal performance.

For a variety of causes, composite crystals have gotten common. These Possess a spatially different chemical composition and can be created with Exclusive shapes.
It could be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It may be preset in certain stable mount which also functions for a warmth sink. Much larger crystals tend to be used for side pumping e.g. with higher-electricity diode bars.
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。
