Fig. 2: High-energy, single-cycle MIR laser source based on the advanced DC-OPA scheme.
From: Dual-chirped optical parametric amplification of high-energy single-cycle laser pulses
BiBO, type-I BiB3O6; MgO:LN, type-I MgO:LiNbO3; BSM, band-stop mirror; CMs, chirped mirrors; AOPDF, acousto-optic programmable dispersive filter; DFG, difference-frequency generation. In the 1st to 3rd DC-OPA stages, the BiBO crystal is in front of the MgO:LN crystal.
