By using a passive Q-switching crystal (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>C</mi><msup><mi>r</mi><mrow><mn>4</mn><mo>+</mo></mrow></msup><mo>:</mo><mi>Y</mi><mi>A</mi><mi>G</mi></mrow></semantics></math></inline-formula>) and a parametric modulation method (harmonic modulation), the stabilization of the laser is reached. An harmonic modulation was applied to the pumping of the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>N</mi><mi>d</mi><mo>:</mo><mi>Y</mi><mi>V</mi><msub><mi>O</mi><mn>4</mn></msub></mrow></semantics></math></inline-formula>-KTP laser to control the amplitude and frequency of the laser emission. The results were characterized by using power spectra analysis, optical spectrum, bifurcation diagrams, and temporal series of the laser intensity. The promising application of this green light source is materialized when such light is necessary for high-density optics, such as in the treatment materials industry or in some aesthetic applications. |
