Abstract: A method of producing a broadband and/or multi-mode emission light source utilizing an Optical Parametric Oscillator (OPO) includes providing a pump source configured to produce a continuous wave pump beam, providing an OPO with an optical cavity containing a nonlinear crystal configured to receive the continuous wave pump beam and produce a first output light beam and a second output light beam. The OPO has an OPO-oscillation threshold level and produces longitudinal mode-scrambling on a resonant OPO-wave. The first output light resonates in the optical cavity in a multi-longitudinal resonant mode and produces a pump beam having a power at least three times the OPO-oscillation threshold.

Abstract: A system includes an optical parametric oscillator (OPO) device. The OPO device has an optical resonator, a first nonlinear optical element (NLO) and a second non-linear optical element (NLO). The first NLO can produce, via OPO of a first pump beam, a first output with a first frequency and a second output with a second frequency. The second frequency is lower than the first frequency. The second NLO can produce, via OPO of a second pump beam (with a higher frequency than the first), a third output with a third frequency and a fourth output with a fourth frequency. The fourth frequency is lower than the third frequency. The first frequency is the same, or at least substantially the same, as the fourth frequency. The OPO device is configured to resonate at the first frequency and the fourth frequency.
