Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent nonlinear optical material well suited for use in several optical programs. It has significant nonlinear coefficient and steady physical assets.

GTR-KTP crystal has gray observe resistance adequately increased than usual flux-grown KTP. It's got broad angular bandwidth and smaller stroll-off angle and wide temperature and spectral bandwidth. GTR-KTP crystals is usually extensively Employed in professional medical, army and meteorology fields.

A compact economical eye-Risk-free intracavity optical parametric oscillator pumped by a passively Q-switched Nd:YAG laser inside a shared cavity configuration with successful conversion performance as significant as 51% is introduced.

                                                                                                 

By way of Photograph-thermal Common-route Interferometer, the prevalence of gray tracking could be measured by a boost of bulk absorption by way of a robust CW 532 nm inexperienced laser in quite a few minutes.

Extremely economical intracavity frequency doubling 532-nm laser depending on the gray monitoring resistance KTP crystal

This phenomenon is correlated with “gray tracking result�? The subsequent graphs display the absorption degree changes as time passes at 1064 nm for CASTECH's GTR-KTP and the traditional KTP individually          

KTP  is an excellent nonlinear crystal, but its grey tracking phenomena  limitations its use in high repetition price and high electrical power laser programs. CASTECH's GTR-KTP crystal has increased gray monitoring resistance than the common flux developed KTP crystal.

Note: Author names are going to be searched while in the keyword phrases area, also, but which could uncover papers wherever the person is described, in lieu of papers they authored.

The crystals are generally accustomed to double the frequency of Nd:YAG and Nd:YVO�?lasers, building noticeable environmentally friendly laser output (532 nm) from the basic 1064 nm wavelength.

                                                             

To realize use more info of this written content, please total the Recommendation Kind and We'll comply with up with all your librarian or Establishment on the behalf.

                                                             

The event of grey-track might be calculated by an increase of bulk absorption by a robust CW 532nm environmentally friendly laser inside of quite a few minutes. This measurement may be done with Image-thermal Typical-path interferometer.
