摘　　要：We investigate the influence of the birefringence on the high-order harmonics in an a-cut Zn O crystal with midinfrared laser pulses.The high harmonics exhibit strong dependence on the alignment of the crystal with respect to the laser polarization.We introduce the Jones calculus to counteract the birefringent effect and obtain the harmonics with polarization corrections in Zn O.We show that the birefringent effect plays an important role in the orientation dependence of HHG.
