    We propose a proof-of-principle experiment to test a new scheme to produce a single-cycle radiation pulse in freeelectron lasers (FELs). Here, a few -BBO crystals will be first used to produce an equally spaced laser pulse train. Then, the laser pulse train illuminates the cathode to produce a frequency-chirped electron bunch train in a photocathode rf gun. Finally, the frequency-chirped electron bunch train passes through a tapered undulator to produce a quasi-singlecycle THz pulse. This experiment should allow comparison and confirmation of predictive models and scaling laws, and the preliminary experimental results will also be discussed.(grants no. 11327902). One of the authors (DX) would like to thank for the support from the Program for Professor of Special Appointment (Eastern Scholar) at Shanghai Institutions of Higher Learning (no. SHDP201507).
