Abstract

We have demonstrated efficient, high-energy, narrow-spectral-bandwidth 2.128 μ m pulse generation by use of periodically poled Mg O : Li Nb O 3 devices with a 36 mm length and a 5 mm × 5 mm large aperture. A free-running degenerated optical parametric oscillator (OPO) pumped with a Q-switched 1.064 μ m Nd:YAG laser exhibits a high slope efficiency of 75% and an optical-to-optical conversion efficiency of 70% with a broad spectral bandwidth ( > 100 nm ) . In a configuration with a spectrally narrowed master oscillator followed by a power amplifier, we have achieved an output pulse energy of 52 mJ with a spectral bandwidth of less than 2 nm at the degeneracy point. The total optical-to-optical conversion efficiency of the system reached 50%.
