The crystallographic dependence of electron emission properties from LaB6 single-crystal tips and its importance has been highlighted in several experimental and theoretical studies. Here, we report on the cold field electron emission from LaB6 nanotips in the orientation under static (DC) and laser-assisted conditions for possible use as an ultrafast electron emitter. By changing the voltage and laser intensity, we observe different emission regimes such as the photo-field emission and the multiphoton photoemission. The field electron microscopy patterns change under ultrafast laser illumination and correspond to the region of a high laser field. The emission properties of LaB6 nanotips in the orientation are compared with those of the orientation.
