Default Need help

I have blue LASER module 50 mw 473nm
Now it not working , I found that the problem from the pump diode (its C - Mount ) , I replaced it with anther one from a good module , and its now working
The problem that I need to Know the spasification of the pump diode (its C-mout Nr. FSY192 ) I can't find the data sheet for it
From searching I find its must be 808nm but i don't know the power of it
what is the suitable power for this module ?

heheh... its "pump" diode. And I think they use 2W diodes, but it really depends on how old it is and who made it.

Thank you very much ,and sorry for my bad English , it's since 2003 by Shimadzu Japan
I measured the voltage was 1.76 V and 1.16 A , Can I use 2W 808nm pump diode ?

Is it safe the higher power not damage the module ?
