Build-up dynamics in an optical parametric oscillator with synchronized pump modulation — •Moritz Floess1, Tobias Steinle1,2, Florian Moerz1, Heiko Linnenbank1, Andy Steinmann1, and Harald Giessen114th Physics Institute and Research Center Scope, University of Stuttgart, D-70569 Stuttgart — 2ICFO - Institut de Ciencies Fotoniques, The Barcelona Institute of Science and Technology, 08860 Castelldefels, Barcelona, Spain

We investigate the build-up dynamics in an optical parametric oscillator (OPO) by synchronously modulating the intensity of the pump beam. An 8-W, 1032-nm, 450-fs Yb:KGW oscillator with 41 MHz repetition rate serves as the OPO pump source. The intensity modulation is realized with an acousto-optical modulator (AOM), which is electronically locked to the repetition rate of the pump laser. The AOM bandwidth of 200 MHz enables shutter times of only ~7 ns. Therefore, the full pump power is available within one laser cycle. This allows to investigate the temporal build-up process of the signal pulses in the OPO cavity. Furthermore, we also have access to the dynamics in the spectral domain by using a dispersive Fourier transformation (DFT) scope, which allows to measure spectra of individual, isolated pulses.
