If you don't discover the ideal products and solutions above, chances are you'll allow us to know your needs or programs in the form beneath. Our revenue or technical staff members will get back again to you as quickly as possible.
If the crystal surfaces are still “dirty�?soon after the above cleaning methods, the surfaces might have been weakened. Be sure to contact us for rework in the crystals.

Commonly, the crystal material should have a large optical transparency for all wavelengths included �?for example, for pump, signal and idler in an optical parametric amplifier.
Also, it can be extremely desirable to make use of a crystal materials that may be critically period-matched at space temperature simply because noncritical section matching generally consists of the Procedure of your crystal inside of a temperature-stabilized crystal oven. On the other hand, the feasibility of vital phase matching can be given only for sufficiently superior peak powers.
Dust and stains on crystal surfaces might cause scattering/reduction of light and can even react with mild to wreck optical surfaces at a substantial incident laser electric power.
Filters below or the shape at the bottom may be used to assist solution lookup get more info or make even more inquiries.
Bismuth Triborate (BiB3O6 or BIBO) can be a freshly formulated nonlinear optical crystal. It possesses large successful nonlinear coefficient, significant hurt threshold and inertness with respect to moisture.
They exhibit excellent homogeneity in excess of substantial volumes and possess a superior hurt threshold, but are hygroscopic and also have a minimal nonlinearity.
Borates such as LBO and BBO also function properly in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Even perfectly down below the edge for fast harm, some crystal resources show a ongoing degradation in the applied quantity, e.
This combination helps make BIBO crystal extremely suited to harnessing the phenomenon of second harmonic era (SHG) in just strong-condition lasers and laser diodes.
Optical crystals can show distinct varieties of optical nonlinearities, which can be utilized in different strategies:
g. in the form of “gray tracking�? These kinds of phenomena are specially popular for operation with ultraviolet light. Be aware that a gradual degradation also can direct into quick catastrophic hurt through extreme heat technology.
