  • The dependence of conversion efficiency and operating lifetime on pump-pulse-repetition rate was systematically studied.

    • Main Results:

    • High laser conversion efficiency was achieved with the developed MPMMA-based materials.
    • A strong nonlinear relationship was observed between pump-pulse-repetition rate and both conversion efficiency and operating lifetime.
    • The study identified a drop in conversion efficiency and useful material lifetime at higher repetition rates.

    Conclusions:

    • MPMMA matrices doped with Rhodamine dyes are effective gain media for laser generation.
    • The pump-pulse-repetition rate significantly impacts the long-term performance and efficiency of these laser materials.
    • Further research into the underlying mechanisms is needed to optimize material stability and laser performance.
