Parametric transfer in a synchronously pumped optical parametric oscillator

Abstract

Abstract:The conditions for high fidelity parametric transfer of the pulse shape of a near-infrared pump pulse to a mid-infrared idler pulse of a synchronously pumped optical parametric oscillator are investigated theoretically and experimentally.

Theoretical and numerical investigations of parametric transfer via difference-frequency generation for indirect mid-infrared pulse shaping

“…30 For example, the necessary narrow spectrum signal pulse could be provided by restricting the spectral bandwidth of the resonating signal pulse using an intra-cavity spectral filter. Such a spectral filter would increase the effective loss of the cavity, and thus the required threshold value.…”
