The TSSG process is a relatively new procedure that has obtained reputation for its capability to deliver high-good quality crystals with small defect density.
In this method, a small seed crystal is placed on best of a supersaturated solution from the beginning supplies, usually Li2O and B2O3, in a development vessel. The answer is then little by little cooled to permit for crystal expansion through the seed crystal.
We offer precision oven and temperature controller to maintain LBO crystals at a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals could be pre-mounted to the oven free of charge in our factory for the ease.
retains a big inventory of LBO crystals which can be delivered in a person 7 days upon receipt of the acquisition buy. (
linear absorption, which can result in heating at higher optical electrical power degrees, so that the period matching is disturbed, and thermal lensing may well arise
A standard system for getting ultrathin crystals is usually to initial optically Get in touch with a thicker nonlinear crystal with a few substrate (e.g. of fused silica) then to shine the crystal down to the required thickness of e.
The Czochralski technique can be a properly-set up procedure for growing large, substantial-quality solitary crystals. It entails melting the setting up products in the crucible and slowly and gradually pulling a seed crystal in the soften when rotating the crystal to keep up uniform expansion.
Whether or not it’s a very low-temperature scientific experiment or even a high-temperature industrial course of action, you'll be able to depend on LBO Crystals to deliver dependable effectiveness. Their means to maintain their nonlinear optical Houses throughout a large temperature variety more augments their flexibility.
In lots of circumstances, a nonlinear crystal utilized for here nonlinear frequency conversion has an exceedingly prolonged life span, and that is extended than that of The entire laser method. The crystal substance is essentially not modified through operation. Even so, a diminished crystal life span can occur under several instances:
The nonlinear optical coefficients of LBO nonlinear crystals Enjoy a vital function in determining the performance of frequency doubling together with other nonlinear optical procedures. The most important coefficient is the second-harmonic era (SHG) coefficient, which is accountable for frequency doubling in LBO crystals.
Superior intensity, small pulse lasers with quick wavelengths have enabled numerous production processes, or improved the results acquired from far more standard lasers. These attributes make attainable a Considerably scaled-down, even negligible HAZ (warmth affected zone) about the location of beam impingement.
Just about the most popular applications is frequency doubling, wherever LBO Crystals efficiently convert the frequency of a large power laser, efficiently halving the wavelength and opening up a spectrum of possibilities for laser programs.
Optical crystals can show distinctive forms of optical nonlinearities, that may be utilized in a variety of ways:
Crystals which can be non-critically section-matched in a crystal oven might exhibit troubles if the crystal temperature is adjusted much too promptly or far too normally. Particularly, anti-reflection coatings could be broken because of various thermal growth coefficients from the involved materials.
