- Abstract
We present a mid-IR tunable high-energy kHz optical parametric oscillator/amplifier (OPO/OPA) based on periodically poled stoichiometric lithium tantalate (PPSLT) nonlinear crystals. These two frequency conversion stages are pumped by a 1-µm-Nd-based master oscillator power amplifier (MOPA) system generating 800 ps pulses at 0.5 kHz with energy scalable up to ~ 40 mJ. The OPO/OPA stages are temperature tunable between 3 and 3.5 µm and provide pulses with energy 4.1 mJ and pulse duration of 600 ps.
