Transient dynamics in a common singly resonant optical parametric oscillator

Large-Scale Spectral Broadening of Femtosecond Optical Parametric Oscillators by MoTe2 Films

“…Optical parametric oscillators (OPOs) have attracted significant attention as a favorable approach to generate tunable coherent light in the spectral regions which are challenging for common active gain materials . Different from common lasers based on stimulated radiation, OPOs rely on nonlinear frequency conversion in nonlinear crystals, which allows for tunable wavelength generation from ultraviolet (UV) to mid-infrared (MIR) regions. − Ultrafast OPOs can deliver picosecond and femtosecond pulses at a repetition rate over several tens of MHz with a peak power of kilowatt or higher. Such OPOs have been considered ideal sources for applications such as driving mid-infrared frequency combs, , exciting nanowire frequency upconversion, , scattering-type scanning near-field optical microscopy (s-SNOM), and coherent Raman scattering (CRS) .…”

Synchronization of Two Indirectly Coupled Singly Resonant Optical Parametric Oscillators

“…Singly resonant optical parametric oscillators (SROs) are obtained once the cavity resonates at a signal frequency [8][9][10][11][12][13]. A qualitative perspective that stimulates the comprehension of SROs features is provided by investigation of the classical characteristics of light emitted from OPOs [14,15].…”

“…A qualitative perspective that stimulates the comprehension of SROs features is provided by investigation of the classical characteristics of light emitted from OPOs [14,15]. The SROs offer single frequency light sources with a narrow linewidth of the output radiation, making these devices highly recommended for a wide area of applications such as remote sensing, spectroscopy analysis, photoelectric detection, and optical frequency division [3][4][5][6][7][8][9][10][11][12][13]. In previous works, the self-sustained oscillations of the field in OPOs devices are treated as a limit-cycle oscillation but the type of the limit-cycle is not investigated [14,16,17].…”
