Xbox 360 Disk Drive

My xbox 360 disk drive has gone, the laser is completely gone. How do I find out which laser I need for the disk drive?

I've been playing my Xbox One for quiet some time, but time has come where I want to go back to 360 where I want to play some of the games I used to play.. I miss playing them.

So question is, what laser do I need for my Disk Drive? Please point me to the directions..
