    Increasing pump power in a laser-diode-pumped Nd:GdVO4 laser caused a transition from irregular to Gaussian lasing patterns. This study explores the underlying physics of these complex laser dynamics.

    Area of Science:

    • Laser physics
    • Nonlinear dynamics
    • Materials science

    Background:

    • Laser-diode-pumped solid-state lasers are crucial for various applications.
    • Understanding transverse mode behavior is essential for laser design and stability.
    • Nd:GdVO4 lasers offer unique properties for high-power operation.

    Purpose of the Study:

    • To investigate the transverse mode transitions in a laser-diode-pumped thin-slice Nd:GdVO4 laser.
    • To analyze the formation of irregular lasing patterns with increasing pump power.

  • Numerical simulations to reproduce observed phenomena.

    • Main Results:

    • An abrupt transition from irregular to Gaussian or billiard-like lasing patterns was observed with increasing pump power.
    • Irregular patterns were attributed to crystal surface roughness and limited transverse confinement.
    • Intensity modulation and chaotic pulsations arose from the interference of transverse modes.

    Conclusions:

    • The study reveals complex transverse mode dynamics in Nd:GdVO4 lasers.
    • Surface imperfections and confinement play a significant role in pattern formation.
    • Numerical simulations validate the physical interpretation of the observed nonlinear laser behavior.
