Developments in synchronously-pumped optical parametric oscillators
The combination of high peak pump power, via synchronous-pumping, with non-critical phase-matching and large nonlinearity via the use of quasi-phase-matched nonlinear media, allows parametric oscillators with very high parametric gain. This high gain can be exploited in a variety of ways, which will be illustrated in this talk with examples of picosecond and femtosecond synchronously-pumped optical parametric oscillators (SPOPOs) based on the use of periodically-poled lithium niobate (PPLN).
These examples include (1) operation at very long idler wavelengths (approaching 7µm) where the idler absorption in PPLN is very strong (~30cm-1), (2) SPOPO with an optical fibre incorporated into the signal feedback path, (3) operation of a SPOPO with a diffraction-grating as the feedback element, (4) a femtosecond SPOPO pumped by a mode-locked fibre laser MOPA system. These unfamiliar operating conditions reveal some interesting new aspects of OPO behaviour, which will be described.

Abstract
The combination of high peak pump power, via synchronous-pumping, with non-critical phase-matching and large nonlinearity via the use of quasi-phase-matched nonlinear media, allows parametric oscillators with very high parametric gain. This high gain can be exploited in a variety of ways, which will be illustrated in this talk with examples of picosecond and femtosecond synchronously-pumped optical parametric oscillators (SPOPOs) based on the use of periodically-poled lithium niobate (PPLN).
These examples include (1) operation at very long idler wavelengths (approaching 7µm) where the idler absorption in PPLN is very strong (~30cm-1), (2) SPOPO with an optical fibre incorporated into the signal feedback path, (3) operation of a SPOPO with a diffraction-grating as the feedback element, (4) a femtosecond SPOPO pumped by a mode-locked fibre laser MOPA system. These unfamiliar operating conditions reveal some interesting new aspects of OPO behaviour, which will be described.
