   Further to this, I've seen Robin Bowden's small video of a laser diode module   
   he zapped with a gas ignitor. All that happened was the laser diode flashed   
   as the ernergy hit it. He protected it with no more that a zener and a low   
   ESR ceramic cap, and maybe a resistor, so if you can protect a laser diode   
   that way, against strong direct repeated hits, I GUARANTEE you can protect a   
   MOSFET.
