We report on the generation and tuning of single-frequency laser light in a monolithic Fabry–Pérot diamond Raman resonator operating visible spectral range. The device was capable squeezing linewidth broad multi-mode nanosecond pump (Δνp= 7.2 ± 0.9 GHz at λp= 450 nm) to nearly Fourier-limited single axial mode Stokes pulse (ΔνS= 114 20 MHz λS= 479 nm). achieved by precise adjustment temperature, with measured frequency-temperature slope ∂ν0/∂T≈ −3 GHz/K, temperature dependence first-order...
This paper presents the general goals of Horizon 2020 project UNCOVER, whose overall purpose is to close gap between academic work and operational needs in fields data-hiding. While digital data-hiding a relatively new area research, our motivation this has been rooted growing community "real-life" scenario object inspection order UNCOVER presence data secretly hidden.
We report on tunable single-frequency monolithic diamond Raman lasers capable of efficiently compressing the linewidth pulsed high power multi-mode by nearly two orders magnitude, approaching Fourier limit.
We study theoretically and experimentally the spectral polarization effects occurring when cascading stimulated Raman scattering processes in diamond. demonstrate an efficient, few-GHz linewidth, broadly tunable, multi-Stokes comb for spectroscopic applications.
