Laser modeling and simulation can be utilized to reliably decide the the best possible crystal Proportions, doping density and possibly values of extra parameters.
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。
The host crystal is way more than simply a way to fix the laser-active ions at specific positions in House. A number of Homes of the host material are very important:
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。
For quasi-three-level laser acquire media and even 3-stage attain media, one typically really should limit the size to a worth that's as well small for efficient pump absorption, as reabsorption effects would otherwise spoil the performance. For aspect pumping, further factors come into Participate in; Other than successful pump absorption, it can be crucial to get a suitable spatial condition from the obtain profile.

A high destruction threshold concerning pulse fluence or peak intensity could be essential for top-Electrical power amplifiers.
These ions permit the crystal to amplify light-weight for the laser wavelength by means of stimulated emission, when Electrical power is equipped to the crystal by using absorption of pump light-weight (�?optical pumping

It may be oriented for close to perpendicular incidence with the laser beam, or at Brewster's angle. It could be mounted in a few stable mount which also functions as being a heat sink. Larger crystals are frequently useful for aspect pumping e.g. with superior-energy diode bars.
The commonest laser-Lively exceptional earth ions and host media together with some typical emission wavelengths are shown in the following desk:
A handful of laser crystal elements have been demonstrated where by some saturable absorber content is included for passive Q switching of the laser.
For several causes, composite crystals have become popular. These Have got a spatially varying chemical composition and may be produced with Specific styles.
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 Nonlinear Crystal that concept, just one won't need to have an extra saturable absorber crystal, to ensure a single may well make more compact Q-switched laser setups with decrease inner parasitic losses. Nonetheless, unwanted Unwanted effects can also happen, for instance acquiring unwanted valence states of the included ions or Power transfers.
