  The study of laser wakefield electron acceleration (LWFA) using mid-IR laser
drivers is a promising path for future laser driven electronaccelerators, when
compared to traditional near-IR laser drivers uperating at 0.8-1 {\mu}m central
wavelength ({\lambda}laser), as the necessary vector potential a_0 for electron
injection can be achieved with smaller laser powers due to the linear
dependence on {\lambda}laser. In this work, we perform 2D PIC simulations on
LWFA using few-cycle high power (5-15 TW) laser systems with {\lambda}laser
ranging from 0.88-10 {\mu}m. Such few-cycle systems are currently under
development, aiming at Gas High Harmonics Generation applications where the
favourable {\lambda}laser^2 scaling extends the range of XUV photon energies.
We keep a_0 and n_e/n_cr (n_e being the plasma density and n_cr being the
critical density for each {\lambda}laser) as common denominators in outr
simulations, allowing for comparisons between drivers of different
{\lambda}laser, with respect to the accelerated electron beam energy, charge,
and conversion efficiency. While the electron energies are mainly dominated by
the plasma dynamics, the laser to electron beam energy conversion efficiency
shows significant enhancement with longer wavelength laser drivers.
