Hello, i have problem ,i found a laser diode from dvd plextor 16x i make the circuit with lm317 i ,i put 6 volts and the mA was about 180mA

and i was waiting to start burn ,i didn't know that i would use a lense to focus the light so i put voltage 12 volts, the mA goes to 250 ,but i let to 250 mA just for 5-10 seconds, it was hot but not so much and now
and now happens this .....

i put 7.2 volts the mA are 200-215 mA the diode is hot if i let it for about 10 seconds ,buttt the light is very small, i does not light as before, why?? I burn it?
tnx
