    "abstract": "We study the energetics of wake excitation during the laser-plasma\ninteraction in application to laser wakefield accelerators. We find that both\nthe wake amplitude and the accelerating efficiency (transformer ratio) can be\nmaximized by properly shaping the longitudinal profile of the driving laser\npulse. The corresponding family of laser pulse shapes is derived in the\nnonlinear regime of laser-plasma interaction. Such shapes provide theoretical\nupper limit on the magnitude of the wakefield and efficiency by allowing for\nuniform photon deceleration inside the laser pulse. We also construct realistic\noptimal pulse shapes that can be produced in finite-bandwidth laser systems.",
