Generation of CEP-stable, octave-spanning MIR pulses based on DC-OPA with two kinds of nonlinear crystals: Towards a TW-class, single-cycle laser source

By combining the dual-chirped optical parametric amplification and two kinds of nonlinear crystal (type-I BiBO and type-I MgO), a one-octave bandwidth (1.45 μm – 3 μm), carrier-to-envelope phase (CEP) stable infrared (IR) laser pulses have been achieved. Our approach will generate several tens of millijoule, single-cycle MIR pulse by taking advantage of a few hundred mJ pump energy and a bulk compressor.
