Narrative:

While descending sebound over the mission bay area at approximately 7000 ft MSL. I first observed a burst of laser light emit from an area to the northeast of san. My perception of this instantaneous event was that the origin point seemed to emit a large burst of multi-colored light, and that a green laser emerged and deflected around inside our cockpit. When we mentioned the presence of laser light activity to the socal approach controller, she responded that they were not aware of any authority/authorized laser activity and that they would verify with the NOTAMS. The aircraft ahead of us on the downwind leg for runway 27 also reported, on the approach control frequency, the presence of green laser light activity. While on the downwind leg, we were able to determine that the light did not emit from qualcom stadium. No further laser light activity was observed while on the base leg, the long final approach leg and the normal landing. The socal controller advised that there was no notamed laser light activity, and that they would investigate further. After arrival san, I immediately notified dispatch. Generally, the emissions originated anywhere from the mission valley area, near the stadium, south to the balboa park area.

Title: A B737-400 EXPERIENCED A LASER LIGHT ENTERING THE FLT STATION ON FINAL APCH.

Narrative: WHILE DSNDING SEBOUND OVER THE MISSION BAY AREA AT APPROX 7000 FT MSL. I FIRST OBSERVED A BURST OF LASER LIGHT EMIT FROM AN AREA TO THE NE OF SAN. MY PERCEPTION OF THIS INSTANTANEOUS EVENT WAS THAT THE ORIGIN POINT SEEMED TO EMIT A LARGE BURST OF MULTI-COLORED LIGHT, AND THAT A GREEN LASER EMERGED AND DEFLECTED AROUND INSIDE OUR COCKPIT. WHEN WE MENTIONED THE PRESENCE OF LASER LIGHT ACTIVITY TO THE SOCAL APCH CTLR, SHE RESPONDED THAT THEY WERE NOT AWARE OF ANY AUTH LASER ACTIVITY AND THAT THEY WOULD VERIFY WITH THE NOTAMS. THE ACFT AHEAD OF US ON THE DOWNWIND LEG FOR RWY 27 ALSO RPTED, ON THE APCH CTL FREQ, THE PRESENCE OF GREEN LASER LIGHT ACTIVITY. WHILE ON THE DOWNWIND LEG, WE WERE ABLE TO DETERMINE THAT THE LIGHT DID NOT EMIT FROM QUALCOM STADIUM. NO FURTHER LASER LIGHT ACTIVITY WAS OBSERVED WHILE ON THE BASE LEG, THE LONG FINAL APCH LEG AND THE NORMAL LNDG. THE SOCAL CTLR ADVISED THAT THERE WAS NO NOTAMED LASER LIGHT ACTIVITY, AND THAT THEY WOULD INVESTIGATE FURTHER. AFTER ARR SAN, I IMMEDIATELY NOTIFIED DISPATCH. GENERALLY, THE EMISSIONS ORIGINATED ANYWHERE FROM THE MISSION VALLEY AREA, NEAR THE STADIUM, S TO THE BALBOA PARK AREA.
