Potassium Titanyl Phosphate (KTiOPO4 or KTP) is a superb nonlinear optical material well suited for use in lots of optical methods. It's got large nonlinear coefficient and stable Bodily property.
Enhanced bulk absorption Homes, lessening IR absorption and enhancing Total optical general performance.
GAMDAN Optics hydrothermally grown KTP crystals Have a very drastically increased grey tracking resistance when compared with flux grown KTP crystals.
Dependant on The grey monitoring resistance (GTR) KTP crystals, the functionality of a high economical and compact intracavity frequency doubling 532 nm laser was investigated. The grey monitoring check…
By Photograph-thermal Frequent-path Interferometer, the incidence of gray monitoring could be measured by an increase of bulk absorption via a sturdy CW 532 nm eco-friendly laser in just many minutes.
Extremely successful intracavity frequency doubling 532-nm laser according to the gray tracking resistance KTP crystal
This phenomenon is correlated with “grey monitoring influence�? The following graphs demonstrate the absorption stage alterations with time at 1064 nm for CASTECH's GTR-KTP and the standard KTP independently
These types of crystals Have a very decreased Original IR absorption and are a lot less influenced by green mild than common KTP, So keep away from the issues of harmonic ability instabilities, efficiency drops, crystal blackening, and beam distortion.
Notice: Author names will be searched while in the key terms area, also, but that will locate papers the place the individual is outlined, rather than papers they authored.
The crystals are generally accustomed to double the frequency of Nd:YAG and click here Nd:YVO�?lasers, creating noticeable green laser output (532 nm) from the elemental 1064 nm wavelength.
The pc you will be working with will not be registered by an institution using a membership to this post. You should pick one of the options under.
Adhesion Check Compliant with MIL-C-675C military benchmarks, an adhesion examination concerned implementing a tape that fulfills LT-ninety requirements onto the lens movie layer. The tape was affixed completely and then taken off vertically. This method was executed 3 times, resulting in no blistering or peeling.
Intracavity optical parametric oscillator at 1572-nm wavelength pumped by passively Q-switched diode-pumped Nd:YAG laser
