Hygroscopic crystal supplies deteriorate when they are not usually kept in adequately dry air (or simply a dry purge fuel). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It might be helpful to maintain this type of crystal in a relatively elevated temperature, which makes it easier to keep it dry.
If the crystal surfaces are still “soiled�?right after the above cleaning treatments, the surfaces may need been broken. Be sure to contact us for rework on the crystals.

The quantity of the solvent is usually adjusted for many crystal dimension Hence the lens tissue is stored moist for the entire drag but there's not any noticeable trace of solvent within the crystal surface once the drag is concluded. Inspect the floor and repeat if vital, but only use Each individual sheet of lens tissue once.
Also, it could be hugely desirable to implement a crystal content which can be critically period-matched at home temperature due to the fact noncritical period matching often entails the operation on the crystal in a very temperature-stabilized crystal oven. However, the feasibility of vital period matching could be offered only for adequately superior peak powers.
Even when the crystal material or coating is not delicate to click here water, compact drinking water droplets may perhaps emphasis laser radiation much more tightly than underneath usual operation, and thus problems the crystal material.
At present, as A sort of wonderful nonlinear second harmonic crystal, it can be used to create substantial efficiency crystal of green or blue laser.
Operation of nonlinear crystals at temperatures beneath home temperature (to achieve phase matching) is normally problematic, as it may well result in condensation of water within the crystal surfaces If your bordering air is not really very dry.
rystal surface is horizontal and a little bit above your fingers. Have a fresh new, cleanse sheet of lens tissue and position it about the crystal. Ensure the lens tissue may be drawn through the crystal area. Following, spot a little drop of pure isopropyl alcohol (IPA) over the lens tissue along with the crystal surface.
the chemical longevity; e.g., some crystal materials are hygroscopic, Other folks bear chemical changes when heated inside a vacuum chamber for application of a dielectric coating
In many scenarios, a nonlinear crystal utilized for nonlinear frequency conversion has a very prolonged lifetime, that's lengthier than that of The full laser method. The crystal substance is actually not modified in the course of Procedure. However, a minimized crystal life time can manifest below a variety of situation:
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
The magnitude on the helpful nonlinear coefficient is determined by the nonlinear tensor components and within the utilized stage-matching configuration. A substantial nonlinearity is crucial particularly When the achievable optical intensities are reduced.
g. in the form of “grey monitoring�? These kinds of phenomena are particularly widespread for Procedure with ultraviolet light. Notice that a gradual degradation may lead into instantaneous catastrophic problems via extreme heat era.
