We report a carrier–envelope-phase-stable 3 μm optical parametric chirped-pulse amplifier (OPCPA), based on periodically poled stoichiometric lithium tantalate nonlinear crystals, which delivers 306 μJ pulse energy at 10 kHz repetition rate and 61 fs pulse width. A 2 mm thick YAG crystal is employed...
