Potassium Titanyl Phosphate (KTiOPO4 or KTP) is a superb nonlinear optical materials appropriate for use in lots of optical units. It has substantial nonlinear coefficient and secure Bodily house.
GTR-KTP crystal has gray track resistance adequately higher than common flux-grown KTP. It has wide angular bandwidth and smaller wander-off angle and wide temperature and spectral bandwidth. GTR-KTP crystals could be broadly Employed in healthcare, armed forces and meteorology fields.
This can be a preview of membership written content, log in by using an establishment to examine obtain. Obtain this text
KTP is an excellent nonlinear crystal, but its grey tracking phenomena limits its use in high repetition price and higher electrical power laser devices. CASTECH's GTR-KTP crystal has increased gray monitoring resistance as opposed to normal flux developed KTP crystal.
The event of grey-monitor is often calculated by a rise of bulk absorption by a strong CW 532nm environmentally friendly laser in just numerous minutes. This measurement is usually performed with Photo-thermal Frequent-route interferometer.

Really effective intracavity frequency doubling 532-nm laser depending on the gray tracking resistance KTP crystal
This phenomenon is correlated with “grey tracking influence�? The following graphs demonstrate the absorption amount modifications after some time at 1064 nm for CASTECH's GTR-KTP and the conventional KTP independently
These kinds of crystals have a decrease Original IR absorption and therefore are fewer affected by eco-friendly light-weight than normal KTP, more info As a result avoid the problems of harmonic electric power instabilities, performance drops, crystal blackening, and beam distortion.
Furthermore, the closed autoclave progress technique permits zero to small chemical impurities plus the frequent advancement level lends a wonderful homogeneity or uniform generate through the bulk crystal.
We current On this report an efficient KTP-centered intracavity optical parametric oscillator pushed by a diode-pumped Nd:GdVO4/Cr:YAG passively Q-switched laser. For the first time, a novel folded…
