 note = {Anisotropy of multiphoton carrier generation in crystalline IIa diamond and its dependence on polarization state of excitation light (near-infrared few-cycle laser pulses) is investigated using photoluminescence and nonlinear absorption measurements. We observe anisotropy between the transition rates for light linearly polarized along <100> and <110> crystallographic directions of diamond and a strong decrease (7-fold) of the transition rate for circularly polarized light. Measured results are compared with numerical simulations using time-dependent density functional theory and with an analytical model assuming a parabolic two-band system and the Houston function as the time-dependent wave function of the valence and conduction bands.},
