Two-Color Tunable Mid-Infrared and Near-Infrared Ultrafast Laser System for Pump-Probe Studies at 1 kHz

Abstract

We built and characterized a DFG mid-infrared source tunable between 4-14 µm and a synchronized 35 fs Ti:Sapphire laser. Mid-infrared XFROG measurements show 200 fs pulse lengths and pump-probe synchronization on a few femtosecond scale.
