Potassium Titanyl Phosphate (KTiOPO4 or KTP) is a wonderful nonlinear optical substance ideal for use in several optical techniques. It's got substantial nonlinear coefficient and stable Bodily property.

Improved bulk absorption Attributes, reducing IR absorption and strengthening Over-all optical performance.

They're manufactured at an optimally low temperature that cuts down the chance of defects, oxygen vacancies, crystal strains, or diminished steel centers.

KTP  is a superb nonlinear crystal, but its grey tracking phenomena  restrictions its use in large repetition level and substantial energy laser programs. CASTECH's GTR-KTP crystal has higher gray monitoring resistance compared to frequent flux grown KTP crystal.

Via Photograph-thermal Frequent-path Interferometer, the event of gray tracking may be measured by an increase of bulk absorption through a strong CW 532 nm green laser within several minutes.

CRYSTECH has much more than 20 years of KTP advancement and processing knowledge. The crystal development system has been optimized to deliver higher-excellent and effective crystals, plus the coating procedure is specially meant to supply a comparatively higher injury threshold.

This phenomenon is correlated with “grey monitoring influence�? The next graphs exhibit the absorption stage variations as time passes at 1064 nm for CASTECH's GTR-KTP and the traditional check here KTP separately          

This kind of crystals Have got a decreased initial IR absorption and are fewer affected by environmentally friendly light-weight than regular KTP, Consequently avoid the issues of harmonic electrical power instabilities, effectiveness drops, crystal blackening, and beam distortion.

In addition, the closed autoclave expansion method permits zero to nominal chemical impurities along with the frequent expansion charge lends an excellent homogeneity or uniform generate all through the bulk crystal. 

The crystals are commonly utilized to double the frequency of Nd:YAG and Nd:YVO�?lasers, generating seen green laser output (532 nm) from the basic 1064 nm wavelength.

To achieve use of this articles, you should complete the Recommendation Variety and We're going to abide by up with all your librarian or Establishment on your own behalf.

Immediately after air drying and subsequent cleansing that has a cotton cloth soaked in Liquor, the film surface area showed no signs of peeling or scratches.

                                                             

Intracavity optical parametric oscillator at 1572-nm wavelength pumped by passively Q-switched diode-pumped Nd:YAG laser
