Abstract

Near single-cycle THz pulse generation from lithium niobate crystal by optical rectification of pulses from an Yb fiber laser/amplifier system was investigated. The pump laser supplied 250 fs long pulses with 14 μJ energy at up to 1 MHz repetition rate. The THz average power exceeded 0.25 mW.
