The crystals are used in medical lasers for strategies for example laser surgical procedures, tattoo elimination, and pores and skin resurfacing, in which steady and reliable laser efficiency is essential.
Comparison in between shared and coupled resonators for passively Q-switched Nd:GdVO4 intracavity optical parametric oscillators
Potassium Titanyl Phosphate crystals (KTP) is Probably the most broadly utilised nonlinear optical crystals in several optical programs. GAMDAN Optics offers GTR (grey tracking resistant) KTP crystals that happen to be hydrothermally grown. We also offer you flux grown KTP and can do the job with our clientele to supply essentially the most acceptable solution for your application.
Compact productive eye-safe intracavity optical parametric oscillator having a shared cavity configuration.
By Image-thermal Popular-path Interferometer, the prevalence of grey tracking can be measured by an increase of bulk absorption by way of a solid CW 532 nm environmentally friendly laser within numerous minutes.
This Site makes use of cookies to provide many of our products and services as well as for analytics and to deliver you a more click here individualized experience.
Extremely efficient intracavity frequency doubling 532-nm laser dependant on the gray tracking resistance KTP crystal
This phenomenon is correlated with “gray tracking result�? The next graphs exhibit the absorption stage variations as time passes at 1064 nm for CASTECH's GTR-KTP and the conventional KTP separately
These crystals have a decrease Original IR absorption and therefore are a lot less affected by eco-friendly gentle than frequent KTP, Hence prevent the issues of harmonic energy instabilities, effectiveness drops, crystal blackening, and beam distortion.
Remarkable damage threshold in contrast to traditional KTP crystals, guaranteeing trustworthiness in demanding purposes.
The crystals are commonly used to double the frequency of Nd:YAG and Nd:YVO�?lasers, building seen inexperienced laser output (532 nm) from the fundamental 1064 nm wavelength.
Soon after air drying and subsequent cleaning having a cotton cloth soaked in Alcoholic beverages, the movie surface showed no signs of peeling or scratches.
Adhesion Take a look at Compliant with MIL-C-675C navy requirements, an adhesion test associated implementing a tape that meets LT-ninety specs onto the lens film layer. The tape was affixed totally after which you can taken out vertically. This process was executed three times, causing no blistering or peeling.
The incidence of grey-track might be calculated by an increase of bulk absorption by a robust CW 532nm green laser inside of quite a few minutes. This measurement may be done with Image-thermal Typical-path interferometer.
