The crystals are used in clinical lasers for methods for instance laser operation, tattoo removal, and skin resurfacing, where by steady and responsible laser efficiency is critical.
Comparison involving shared and coupled resonators for passively Q-switched Nd:GdVO4 intracavity optical parametric oscillators
Potassium Titanyl Phosphate crystals (KTP) is one of the most broadly applied nonlinear optical crystals in lots of optical systems. GAMDAN Optics provides GTR (gray tracking resistant) KTP crystals which can be hydrothermally developed. We also offer flux grown KTP and will work with our customers to deliver quite possibly the most appropriate Option for your personal application.
Determined by the gray monitoring resistance (GTR) KTP crystals, the effectiveness of a large economical and compact intracavity frequency doubling 532 nm laser was investigated. The gray monitoring test…
By means of Picture-thermal Typical-route Interferometer, the event of gray monitoring is often measured by an increase of bulk absorption via a solid CW 532 nm eco-friendly laser within numerous minutes.
CASTECH's GRT-KTP, as a fantastic NLO crystal, has lower absorption and higher problems threshold than the traditional KTP, which we can conclude it possesses a better grey monitor resistance.
This phenomenon is correlated with “grey monitoring outcome�? The next graphs demonstrate the absorption amount adjustments after some time at 1064 nm for CASTECH's GTR-KTP and the traditional KTP independently
KTP is an excellent nonlinear crystal, but its grey monitoring phenomena restrictions its use in significant repetition price check here and large electric power laser systems. CASTECH's GTR-KTP crystal has higher grey monitoring resistance compared to frequent flux developed KTP crystal.
In addition, the closed autoclave growth method allows for zero to minimal chemical impurities and also the continuous development charge lends a superb homogeneity or uniform yield through the entire bulk crystal.
Substantial gray monitoring resistance, making it perfect for substantial repetition price and superior-electric power laser techniques.
GTR-KTP crystals, created with impressive producing processes, exhibit appreciably higher resistance to gray tracking and decreased absorption in the UV and visible areas, building them suitable for a wide range of programs for instance frequency doubling, parametric oscillation, and laser amplification.
Just after air drying and subsequent cleansing that has a cotton fabric soaked in Liquor, the film surface showed no indications of peeling or scratches.
Adhesion Exam Compliant with MIL-C-675C navy specifications, an adhesion test associated making use of a tape that satisfies LT-90 specifications on to the lens film layer. The tape was affixed thoroughly then eliminated vertically. This course of action was carried out thrice, causing no blistering or peeling.
Intracavity optical parametric oscillator at 1572-nm wavelength pumped by passively Q-switched diode-pumped Nd:YAG laser
