I do not know of any list of diodes, and what DTR carry in stock of LD`s is what is used.
C-mounted diodes are used in pumped lasers, but i don`t know of any pure diode modules using them. From what i have read , they produce a rather nasty beam, even if corrected.
For higher powers, two or more diodes are combined by PBS or knife edging.
But there are development, and new LD`s are coming out more or less all the time.
The 1W 520nm diode is a god example.
Keep on reading PL, and you will gain the knowlage and information you need to do some amazing stuff.
