Narrative:

Unknown persons on the ground illuminated our flight with a green laser. On approach to sna; our airplane was illuminated by a green laser originating from south palos verdes area. I called laser illumination. The laser activity lasted about 3 seconds. We reported the illumination to socal approach. The flight continued to land uneventfully. I would strongly recommend that aircrews be reminded to report laser activity to ATC the instant it occurs as incapacitation is a serious possibility. First officer noticed the illumination and took reactive action immediately.
