Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent nonlinear optical material well suited for use in lots of optical programs. It's higher nonlinear coefficient and secure Bodily house.
Improved bulk absorption Houses, lessening IR absorption and improving Total optical functionality.
They can be produced at an optimally small temperature that reduces the probability of defects, oxygen vacancies, crystal strains, or diminished steel centers.
A compact productive eye-Protected intracavity optical parametric oscillator pumped by a passively Q-switched Nd:YAG laser in a shared cavity configuration with effective conversion efficiency as large as fifty one% is presented.
By Image-thermal Frequent-path Interferometer, the prevalence of gray tracking is often calculated by a rise of bulk absorption by way of a strong CW 532 nm green laser in several minutes.
CASTECH's GRT-KTP, as an excellent NLO crystal, has lower absorption and better hurt threshold than the conventional KTP, which we can easily conclude it possesses the next gray observe resistance.
This phenomenon is correlated with “grey tracking effect�? The next graphs show the absorption degree alterations over time at 1064 nm for CASTECH's GTR-KTP and the conventional KTP separately
Flux grown KTP crystals supply an improved rate gain. It is usually conveniently fabricated in more substantial dimensions.
Furthermore, the shut autoclave advancement system allows for zero to minimal chemical impurities and the continuous development price lends a great homogeneity or uniform yield through the entire bulk crystal.
The crystals are commonly used to double the frequency of Nd:YAG and Nd:YVO�?lasers, generating obvious inexperienced laser output (532 nm) from the basic 1064 nm wavelength.
To achieve usage of this material, you should total the Recommendation Variety and We'll comply with up with your librarian or Institution on your own behalf.
Following air drying and subsequent cleaning with a cotton fabric soaked in Liquor, the film surface showed no indications of peeling or scratches.
Advanced producing processes ensuring click here Remarkable grey tracking resistance and optical Attributes.
The event of grey-track might be calculated by a rise of bulk absorption by a solid CW 532nm eco-friendly laser in just several minutes. This measurement is usually executed with Image-thermal Popular-route interferometer.
