(a) Schematic of the experimental setup. TFP, thin-film polarizer: AOTF, acousto-optic tunable filter; M1, folding pump mirror; M2, folding mirror for extracting the idler; M3, output coupler for the ET-Cr:ZnSe laser; and M4, total reflector. (b) PM tuning curve for type-1 DFG in ZGP at 20 °C. Pump and signal waves are given by the Tm:YAG laser (2.013 μm) and ET-Cr:ZnSe laser, respectively.
