Laser modeling and simulation may be used to reliably identify the ideal crystal Proportions, doping density And perhaps values of additional parameters.
The medium should have a significant transparency (low absorption and scattering) inside the wavelength locations of pump and laser radiation, and good optical homogeneity. To some extent, this is determined by the standard of the fabric, based on particulars in the fabrication course of action.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and also the upper-state life span.
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。
The maximum attainable doping focus can depend strongly over the host content and its fabrication process.

GWU-Lasertechnik has a lot more than 30 years of working experience in distributing laser crystals. Opt for GWU to get pleasure from our extensive understanding As well as in-subject expertise!
A significant injury threshold concerning pulse fluence or peak intensity is usually crucial for top-Vitality amplifiers.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
Which geometry, dopant and doping focus of the obtain medium are most useful count on numerous components. The available pump supply (style of laser diode or lamp) and the envisaged pumping arrangement are essential variables, but the fabric alone also has some impact. For instance, titanium–sapphire lasers must be pumped with significant intensities, for which the shape of the transversely cooled rod, operated with relatively tiny pump and laser beam diameter, is much more acceptable than e.
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in some strong mount which also acts as being a heat sink. get more info Greater crystals are frequently employed for aspect pumping e.g. with large-electricity diode bars.
The most common laser-Lively scarce earth ions and host media along with some standard emission wavelengths are shown in the subsequent desk:
Several laser crystal products have already been shown in which some saturable absorber product is incorporated for passive Q switching of the laser.
For various motives, composite crystals are becoming well-known. These Have got a spatially varying chemical composition and may be built with Unique designs.
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。
With that concept, a single isn't going to need to have a further saturable absorber crystal, making sure that just one may make extra compact Q-switched laser setups with lessen interior parasitic losses. Having said that, unwelcome side effects may also manifest, which include getting undesired valence states in the involved ions or energy transfers.
GWU gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) which has a wide selection of specifications. Besides the very well-proven supplies, innovative crystals with remarkable Homes like Yb:CALGO can open up new horizons for demanding laser apps. Regardless of whether particular person pieces for R & D applications are required or cost-productive numbers in modest, medium or big batches with in-time shipping for the generation line are required: GWU’s committed service helps you to locate the very best core factors for the software.
Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical products) �?which can be applied as gain media for sound-point out lasers. In most cases, They may be doped with both trivalent scarce earth ions or transition metal ions.
