Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent nonlinear optical material suitable for use in lots of optical systems. It has significant nonlinear coefficient and stable physical residence.
GTR-KTP crystal has grey observe resistance sufficiently greater than regular flux-grown KTP. It's got broad angular bandwidth and smaller walk-off angle and wide temperature and spectral bandwidth. GTR-KTP crystals can be commonly Employed in medical, armed forces and meteorology fields.
They may be created at an optimally low temperature that lessens the probability of defects, oxygen vacancies, crystal strains, or diminished steel facilities.
Depending on the gray tracking resistance (GTR) KTP crystals, the effectiveness of the higher successful and compact intracavity frequency doubling 532 nm laser was investigated. The grey monitoring examination…
The event of gray-track might be calculated by an increase of bulk absorption by a robust CW 532nm inexperienced laser within various minutes. This measurement may be carried out with Photo-thermal Common-path interferometer.
Q Exactly what is green semico... A At the moment, the Doing the job basic principle of inexperienced semiconductor laser is to transform 1064nm infrared light-weight emitted by infrared semiconductor laser into 532nm environmentally friendly mild through nonlinear crystallization. Gre
CRYSTECH has much more than twenty years of check here KTP advancement and processing encounter. The crystal development system has long been optimized to deliver large-high quality and successful crystals, as well as coating method is specially made to give a comparatively bigger destruction threshold.
This phenomenon is correlated with “gray monitoring outcome�? The following graphs demonstrate the absorption amount adjustments eventually at 1064 nm for CASTECH's GTR-KTP and the conventional KTP separately
This kind of crystals Use a lessen First IR absorption and they are a lot less afflicted by environmentally friendly light than common KTP, Hence avoid the problems of harmonic electric power instabilities, efficiency drops, crystal blackening, and beam distortion.
Also, the shut autoclave progress technique permits zero to small chemical impurities plus the constant expansion level lends an excellent homogeneity or uniform generate through the entire bulk crystal.
The crystals are commonly accustomed to double the frequency of Nd:YAG and Nd:YVO�?lasers, creating visible environmentally friendly laser output (532 nm) from the fundamental 1064 nm wavelength.
GTR-KTP crystals, made with ground breaking producing procedures, exhibit drastically bigger resistance to grey tracking and reduced absorption while in the UV and visible areas, making them ideal for an array of applications like frequency doubling, parametric oscillation, and laser amplification.
Right after air drying and subsequent cleansing which has a cotton cloth soaked in Liquor, the movie floor showed no indications of peeling or scratches.
Adhesion Check Compliant with MIL-C-675C armed service standards, an adhesion exam concerned making use of a tape that fulfills LT-90 specifications on to the lens movie layer. The tape was affixed entirely then removed vertically. This process was performed 3 times, causing no blistering or peeling.
With their broad spectral assortment and low IR absorption, GTR-KTP crystals are very well-suited for spectroscopic instruments and Superior imaging technologies.
