A high stability electron bunch is generated by laser wakefield acceleration with the help of a colliding laser pulse. The wakefield is generated by a laser pulse; the second laser pulse collides with the first pulse at 180$$^{circ}$$ and at 135$$^{circ}$$ realizing optical injection of an electron bunch. The electron bunch has high stability and high reproducibility compared with single pulse electron generation. In the case of 180$$^{circ}$$ collision, special measures have been taken to prevent damage. In the case of 135$$^{circ}$$ collision, since the second pulse is counter-crossing, it can not damage the laser system.
