450 gatling laser diode replacement

[Seizedupp]

hi, awhile back i bought a 1mw 450nm blue laser(gatling) and the diode burned out pretty quickly, i want to replace it but need help finding the right diode, can any help me with this or give me a link to where i can get this?

I believe the Osram PLTB450B 1.6W 450nm from DTR's Laser shop should be sufficient. It's pretty cheap at 23 dollars. Good luck on your project
