Distinctive crystalline resources are quite unique regarding their hardness together with other Houses, which determine with which methods And the way effortlessly they can be cut and polished with good quality.
The medium must have a significant transparency (small absorption and scattering) while in the wavelength areas of pump and laser radiation, and excellent optical homogeneity. To some extent, this will depend on the caliber of the material, based on particulars of the fabrication method.
The host crystal is far more than simply a way to repair the laser-active ions at selected positions in Room. Numerous Attributes of the host product are crucial:
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-a few-level laser achieve media or perhaps a few-level obtain media, a person normally ought to Restrict the size to a worth which can be too quick for effective pump absorption, as reabsorption results would in any other case spoil the effectiveness. For aspect pumping, additional criteria appear into Enjoy; Apart from productive pump absorption, it is necessary to obtain an appropriate spatial condition of the acquire profile.
g. a thin disk. As Yet another case in point, Q-switched lasers reach a higher population density in the upper laser stage and are consequently much more delicate to quenching results and energy transfer procedures; consequently, a decreased doping density is frequently suitable for these gadgets. For top-energy lasers, decrease doping densities are frequently accustomed to Restrict the density of warmth technology, Though thin-disk lasers get the job done greatest with extremely doped crystals. Many laser solutions usually do not get to the complete performance possible simply because these kinds of specifics have not been properly labored out.
GWU-Lasertechnik has over 30 several years of knowledge in distributing laser crystals. Opt for GWU to benefit from our wide expertise and in-field knowledge!
A significant injury threshold when it comes to pulse fluence or peak depth is usually read more crucial for prime-Power amplifiers.
These ions empower the crystal to amplify light for the laser wavelength via stimulated emission, when Vitality is provided into the crystal via absorption of pump gentle (�?optical pumping

It might be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It may be fastened in certain sound mount which also acts for a warmth sink. Larger crystals are frequently useful for facet pumping e.g. with high-energy diode bars.
The most common laser-Lively rare earth ions and host media together with some standard emission wavelengths are proven in the subsequent table:
Several laser crystal resources are already shown exactly where some saturable absorber material is incorporated for passive Q switching of a laser.
For many reasons, composite crystals have become well-liked. These Have got a spatially varying chemical composition and might be manufactured with Specific styles.
There's an array of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline buildings. Some essential teams of crystals are:

GWU features all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) having a broad variety of technical specs. Other than the properly-set up supplies, innovative crystals with superb Houses like Yb:CALGO can open new horizons for demanding laser purposes. Despite no matter whether personal parts for R & D functions are necessary or Expense-successful numbers in tiny, medium or significant batches with in-time delivery to the creation line are desired: GWU’s dedicated support helps to find the most effective Main factors in your application.
It is clear that distinctive purposes bring about extremely different prerequisites on laser achieve media. Due to this, a wide vary of different crystals are utilised, and making the best choice is essential for constructing lasers with optimum general performance.
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。
