Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent nonlinear optical product suited to use in many optical devices. It has significant nonlinear coefficient and stable Actual physical home.
GTR-KTP crystal has grey monitor resistance adequately better than typical flux-grown KTP. It's wide angular bandwidth and tiny stroll-off angle and wide temperature and spectral bandwidth. GTR-KTP crystals may be broadly Utilized in health care, military and meteorology fields.
GAMDAN Optics hydrothermally grown KTP crystals Possess a considerably higher gray monitoring resistance as compared to flux developed KTP crystals.
A compact successful eye-Harmless intracavity optical parametric oscillator pumped by a passively Q-switched Nd:YAG laser within a shared cavity configuration with powerful conversion effectiveness as higher as fifty one% is presented.
Via Photograph-thermal Common-path Interferometer, the occurrence of grey monitoring may be measured by a rise of bulk absorption through a powerful CW 532 nm environmentally friendly laser in many minutes.
CASTECH's GRT-KTP, as a great NLO crystal, has decrease absorption and higher injury threshold than the standard KTP, which we can easily conclude it possesses the next gray track resistance.
This phenomenon is correlated with “grey monitoring outcome�? The next graphs clearly show the absorption level improvements with time at 1064 nm for CASTECH's GTR-KTP and the traditional KTP individually
KTP is an excellent nonlinear crystal, but its gray monitoring phenomena boundaries its use in large repetition price and significant energy laser systems. CASTECH's GTR-KTP crystal has better gray monitoring resistance compared to frequent flux grown KTP crystal.
Also, the closed autoclave growth process permits zero to minimal chemical impurities as well as continuous progress price lends an outstanding homogeneity or uniform yield throughout the bulk crystal.
High grey monitoring resistance, rendering it ideal for substantial repetition fee and significant-electricity laser techniques.
GTR-KTP crystals, designed with modern manufacturing processes, show significantly better resistance to gray monitoring and lower absorption inside the UV and visual areas, creating them suited to a variety of applications like frequency doubling, parametric oscillation, and laser amplification.
Soon after air drying and subsequent cleansing which has a cotton fabric soaked in Liquor, the film surface showed no indications of peeling or scratches.
Adhesion click here Take a look at Compliant with MIL-C-675C military services expectations, an adhesion check associated making use of a tape that meets LT-ninety specifications on to the lens film layer. The tape was affixed absolutely and afterwards eliminated vertically. This course of action was done three times, leading to no blistering or peeling.
Intracavity optical parametric oscillator at 1572-nm wavelength pumped by passively Q-switched diode-pumped Nd:YAG laser
