Luminescent and lasing properties at the {sup 4}F{sub 3/2} - {sup 4}I{sub 11/2} transition of {alpha}-cut Nd:YVO{sub 4}, Nd:GdVO{sub 4}, Nd:Gd{sub 1-x}Y{sub x}VO{sub 4} and Nd:Sc{sub 1-x}Y{sub x}VO{sub 4} vanadate crystals are experimentally studied for {pi}- and {sigma}-polarisations. Polarisation dependences of the lasing characteristics of passively Q-switched Nd:YVO{sub 4}, Nd:Gd{sub 1-x}Y{sub x}VO{sub 4} and Nd:Sc{sub 1-x}Y{sub x}VO{sub 4} lasers with Cr{sup 4+}:YAG and V{sup 3+}:YAG Q-switches are investigated. It is shown that the laser wavelengths are different for {pi}- and {sigma}-polarizations. The best characteristics are achieved for the Nd:YVO{sub 4} laser with a Cr{sup 4+}:YAG passive saturable absorber for {sigma}-polarisation (minimum pulse duration shorter than 3 ns, maximum peak power up to 10 kW, maximum peak energy {approx}35 {mu}J at a slope efficiency up to 32%).
