Potassium Titanyl Phosphate (KTiOPO4 or KTP) is a wonderful nonlinear optical substance appropriate for use in many optical devices. It has superior nonlinear coefficient and steady physical residence.
Comparison among shared and coupled resonators for passively Q-switched Nd:GdVO4 intracavity optical parametric oscillators
They are made at an optimally very low temperature that minimizes the probability of defects, oxygen vacancies, crystal strains, or lowered steel centers.
A compact productive eye-Harmless intracavity optical parametric oscillator pumped by a passively Q-switched Nd:YAG laser inside of a shared cavity configuration with successful conversion effectiveness as substantial as fifty one% is introduced.
The incidence of grey-track may be measured by a rise of bulk absorption by a solid CW 532nm green laser within various minutes. This measurement is usually performed with Photograph-thermal Prevalent-path interferometer.
As a result of Image-thermal Common-route Interferometer, the prevalence of gray monitoring could be calculated by an increase of bulk absorption via a sturdy CW 532 nm environmentally friendly laser inside of a number of minutes.
CASTECH's GRT-KTP, more info as a superb NLO crystal, has decreased absorption and better damage threshold than the traditional KTP, which we could conclude it possesses the next gray monitor resistance.

Flux grown KTP crystals present a greater price edge. It is additionally quickly fabricated in larger dimensions.
Also, the shut autoclave expansion process permits zero to minimal chemical impurities plus the consistent development charge lends a superb homogeneity or uniform yield through the entire bulk crystal.
We existing During this report an successful KTP-based mostly intracavity optical parametric oscillator driven by a diode-pumped Nd:GdVO4/Cr:YAG passively Q-switched laser. For The 1st time, a novel folded…
