5 Simple Techniques For GTR-KTP Crystal
Blog Article
The crystals are Employed in professional medical lasers for methods for instance laser surgical procedure, tattoo removal, and pores and skin resurfacing, wherever stable and reputable laser overall performance is vital.
GTR-KTP crystal has gray track resistance sufficiently larger than normal flux-grown KTP. It has wide angular bandwidth and smaller walk-off angle and wide temperature and spectral bandwidth. GTR-KTP crystals is often extensively Utilized in professional medical, army and meteorology fields.

KTP is an excellent nonlinear crystal, but its grey tracking phenomena boundaries its use in higher repetition level and significant electrical power laser systems. CASTECH's GTR-KTP crystal has increased grey monitoring resistance as opposed to frequent flux grown KTP crystal.
As a result of Photo-thermal Typical-path Interferometer, the incidence of gray monitoring is often calculated by a boost of bulk absorption via a potent CW 532 nm eco-friendly laser inside of various minutes.

This phenomenon is correlated with “grey tracking result�? The next graphs exhibit the absorption amount improvements over time at 1064 nm for CASTECH's GTR-KTP and the conventional KTP individually
This sort of crystals have a decrease Original IR absorption and therefore are less afflicted by environmentally friendly mild than frequent KTP, Hence steer clear of the issues of harmonic power instabilities, efficiency drops, crystal blackening, and beam distortion.
Note: Author names is going to be searched from the key terms industry, also, but that could come across papers exactly where the person is stated, in lieu of papers they authored.
The crystals are commonly utilized to double the frequency of Nd:YAG and Nd:YVO�?lasers, making noticeable green laser output (532 nm) from the elemental 1064 nm wavelength.

Adhesion Check Compliant with MIL-C-675C army standards, an adhesion take a look at concerned implementing a tape that meets LT-90 technical specs onto the lens movie layer. The tape was affixed absolutely then removed vertically. This technique was performed 3 times, causing no blistering or peeling.
The incidence of gray-observe is often calculated by a rise of bulk absorption by a robust CW 532nm inexperienced laser within just quite a few minutes. This measurement is usually executed with Photograph-thermal Typical-path interferometer.
