| Abstract | Sources of intense, ultra-short electromagnetic pulses are enabling applications such as attosecond pulse generation, control of electron motion in solids and the observation of reaction dynamics at the electronic level. For such applications both high-intensity and carrier envelope phase (CEP) tunability is beneficial, yet hard to obtain with current methods. In this work we present a new scheme for generation of isolated CEP-tunable intense sub-cycle pulses with significant spectral power from mid-IR to UV. It utilizes an intense driver laser pulse which drives a wake in a plasma, co-propagating with a long-wavelength seed pulse. The moving electron density peaks of the wake amplify the seed and form sub-cycle pulses. Controlling the CEP of the seed pulse or the driver-seed delay leads to CEP-tunability, while frequency tunability can be achieved by adjusting the laser and plasma parameters. Our 2D and 3D Particle-In-Cell simulations predict laser-to-sub-cycle-pulse conversion efficiencies up to 1% suggesting the possibility to create tens of mJ strong sub-cycle pulses. |
